Question
In part of the figure, particle l (of charge q_1) and particle 2 (of charge q_2) are fixed in place on an x axis, 16.00 cm apart. Particle 3 (of charge q_3 = +8.00 times 10^-19 C) is to be placed on the line between particles 1 and 2 so that they produce a net electrostatic force on It. In part of the figure below gives the x component of that force versus the coordinate x at which particle 3 is placed. The scale of the x axis is set by x, - 16.00 cm. What are the sign of charge q_1 and (the ratio q_2/q_1?Explanation / Answer
a] positive because just to right of particle 1, particle 3 of positive charge experience force in x direction.
b] kq1/r1^2 = kq2/r2^2
q2/q1 = [r2/r1]^2
= 3^2
= 9 answer
