Question
Particles of chager +75, +45, and -85 micrometers are placedin a line. The center one is .35 m from each of theothers. Calculated the net force on each charge due tothe other two. This is the question that i am having trouble with cansomeone please help me!! Particles of chager +75, +45, and -85 micrometers are placedin a line. The center one is .35 m from each of theothers.

Explanation / Answer
force on 45 C charge due to 75 C charge is F = K q q ' / r ^ 2 where K = coulomb's constant = 8.99 * 10 ^ 9 N m ^2 / C ^ 2 q = 45 * 10 ^ -6 C q ' = 75 * 10 ^ -6 C r = 0.35 m plug the values weegt F value force on 45 C charge due to -85 Ccharge is F ' = K q q " / r ^ 2 where K = coulomb's constant = 8.99 * 10 ^ 9 N m ^2 / C ^ 2 q = 45 * 10 ^ -6 C q " = -85 * 10 ^ -6 C r = 0.35 m plug the values weegt F' value So, net force on 45 C is = F + F ' (b). force on 75 C charge due to 45 C charge is F = K q q ' / r ^ 2 where K = coulomb's constant = 8.99 * 10 ^ 9 N m ^2 / C ^ 2 q = 45 * 10 ^ -6 C q ' = 75 * 10 ^ -6 C r = 0.35 m plug the values weegt F value force on 75 C charge due to -85 Ccharge is F ' = K q 'q " / r ' ^2 where K = coulomb's constant = 8.99 * 10 ^ 9 N m ^2 / C ^ 2 q = 75 * 10 ^ -6 C q " = -85 * 10 ^ -6 C r = 0.35 m +0.35 m = 0.7 m plug the values weget F' value So, net force on 75 C is = F + F ' (c). force on -85 C charge due to 75 C charge is F = K q " q ' / r ^ 2 where K = coulomb's constant = 8.99 * 10 ^ 9 N m ^2 / C ^ 2 q " = -85 * 10 ^ -6 C q ' = 75 * 10 ^ -6 C r = 0.7 m plug the values weegt F value force on -85 C charge due to 45 Ccharge is F ' = K q q " / r ^ 2 where K = coulomb's constant = 8.99 * 10 ^ 9 N m ^2 / C ^ 2 q = 45 * 10 ^ -6 C q " = -85 * 10 ^ -6 C r = 0.35 m plug the values weegt F' value So, net force on -85 C is = F + F ' force on 45 C charge due to -85 Ccharge is F ' = K q q " / r ^ 2 where K = coulomb's constant = 8.99 * 10 ^ 9 N m ^2 / C ^ 2 q = 45 * 10 ^ -6 C q " = -85 * 10 ^ -6 C r = 0.35 m plug the values weegt F' value So, net force on 45 C is = F + F ' (b). force on 75 C charge due to 45 C charge is F = K q q ' / r ^ 2 where K = coulomb's constant = 8.99 * 10 ^ 9 N m ^2 / C ^ 2 q = 45 * 10 ^ -6 C q ' = 75 * 10 ^ -6 C r = 0.35 m plug the values weegt F value force on 75 C charge due to -85 Ccharge is F ' = K q 'q " / r ' ^2 where K = coulomb's constant = 8.99 * 10 ^ 9 N m ^2 / C ^ 2 q = 75 * 10 ^ -6 C q " = -85 * 10 ^ -6 C r = 0.35 m +0.35 m = 0.7 m plug the values weget F' value So, net force on 75 C is = F + F ' (c). force on -85 C charge due to 75 C charge is F = K q " q ' / r ^ 2 where K = coulomb's constant = 8.99 * 10 ^ 9 N m ^2 / C ^ 2 q " = -85 * 10 ^ -6 C q ' = 75 * 10 ^ -6 C r = 0.7 m plug the values weegt F value force on -85 C charge due to 45 Ccharge is F ' = K q q " / r ^ 2 where K = coulomb's constant = 8.99 * 10 ^ 9 N m ^2 / C ^ 2 q = 45 * 10 ^ -6 C q " = -85 * 10 ^ -6 C r = 0.35 m plug the values weegt F' value So, net force on -85 C is = F + F ' force on 75 C charge due to 45 C charge is F = K q q ' / r ^ 2 where K = coulomb's constant = 8.99 * 10 ^ 9 N m ^2 / C ^ 2 q = 45 * 10 ^ -6 C q ' = 75 * 10 ^ -6 C r = 0.35 m plug the values weegt F value force on 75 C charge due to -85 Ccharge is F ' = K q 'q " / r ' ^2 where K = coulomb's constant = 8.99 * 10 ^ 9 N m ^2 / C ^ 2 q = 75 * 10 ^ -6 C q " = -85 * 10 ^ -6 C r = 0.35 m +0.35 m = 0.7 m plug the values weget F' value So, net force on 75 C is = F + F ' (c). force on -85 C charge due to 75 C charge is F = K q " q ' / r ^ 2 where K = coulomb's constant = 8.99 * 10 ^ 9 N m ^2 / C ^ 2 q " = -85 * 10 ^ -6 C q ' = 75 * 10 ^ -6 C r = 0.7 m plug the values weegt F value force on -85 C charge due to 45 Ccharge is F ' = K q q " / r ^ 2 where K = coulomb's constant = 8.99 * 10 ^ 9 N m ^2 / C ^ 2 q = 45 * 10 ^ -6 C q " = -85 * 10 ^ -6 C r = 0.35 m plug the values weegt F' value So, net force on -85 C is = F + F ' force on 75 C charge due to -85 Ccharge is F ' = K q 'q " / r ' ^2 where K = coulomb's constant = 8.99 * 10 ^ 9 N m ^2 / C ^ 2 q = 75 * 10 ^ -6 C q " = -85 * 10 ^ -6 C r = 0.35 m +0.35 m = 0.7 m plug the values weget F' value So, net force on 75 C is = F + F ' (c). force on -85 C charge due to 75 C charge is F = K q " q ' / r ^ 2 where K = coulomb's constant = 8.99 * 10 ^ 9 N m ^2 / C ^ 2 q " = -85 * 10 ^ -6 C q ' = 75 * 10 ^ -6 C r = 0.7 m plug the values weegt F value force on -85 C charge due to 45 Ccharge is F ' = K q q " / r ^ 2 where K = coulomb's constant = 8.99 * 10 ^ 9 N m ^2 / C ^ 2 q = 45 * 10 ^ -6 C q " = -85 * 10 ^ -6 C r = 0.35 m plug the values weegt F' value So, net force on -85 C is = F + F ' force on -85 C charge due to 75 C charge is F = K q " q ' / r ^ 2 where K = coulomb's constant = 8.99 * 10 ^ 9 N m ^2 / C ^ 2 q " = -85 * 10 ^ -6 C q ' = 75 * 10 ^ -6 C r = 0.7 m plug the values weegt F value force on -85 C charge due to 45 Ccharge is F ' = K q q " / r ^ 2 where K = coulomb's constant = 8.99 * 10 ^ 9 N m ^2 / C ^ 2 q = 45 * 10 ^ -6 C q " = -85 * 10 ^ -6 C r = 0.35 m plug the values weegt F' value So, net force on -85 C is = F + F ' force on -85 C charge due to 45 Ccharge is F ' = K q q " / r ^ 2 where K = coulomb's constant = 8.99 * 10 ^ 9 N m ^2 / C ^ 2 q = 45 * 10 ^ -6 C q " = -85 * 10 ^ -6 C r = 0.35 m plug the values weegt F' value So, net force on -85 C is = F + F '
