Explanation / Answer

(16) A particle with charge 2 µC is located on the x-axis at the point -6 cm, and a second particle with charge 8 µC is placed on the x-axis at 4 cm.

The Coulomb constant is 8.9875 × 10^9 N m2/C2.

the magnitude of the total electrostatic force on a third particle with charge 7 µC placed on the x-axis at 2 cm.

k = 8.9875 * 10^9

q1 = 2 * 10^-6 C

q2 = 8 * 10^-6 C

q3 = 7 * 10^-6 C

r1 = 0.08 m

r2 = 0.02 m

F_total = (k * q3 * q1 / r2^2) + (k * q3 * q2 / r1^2)

= (8.9875*10^9 * 7*10^-6 * 2*10^-6 /0.02^2)+(8.9875*10^9 * 7*10^-6 * 8*10^-6 /0.08^2)

F_total= 393.203 N
