Question

A charge, Q2 = -5.00x10^-6 C, is 15.00 cm to the right of charge Q1 = 14.00x10^-6 C. Where can a third charge be placed, along the line connecting Q1 and Q2, such that it experiences no net force (other than ±∞)? Give distances relative to Q1 and use a plus sign if the third charge is to the right of Q1 (and negative sign if the charge is to the left).

Problem 5 A charge 2-5.00x10 6 C is 15.00 cm to the right of charge Q1-14.0 x 10-6 C where can a third charge be placed along the line connecting distances relative to Ql and use a plus sign if the third charge is to the right of Q1 (and negative sign if the charge is to the left) 1 and Q2 such that it experiences no net force (other than ± )?

Answer 1

Theta_1 theta_3/4 pi E_0 x^2 = theta_2 theta_3/4 lambda E_0 (x - 015)^2 x - 0.15/x = squareroot 5 times 10^- 6/14 times 10^- 6 x = 0.15/1 - squareroot 5/14 = 0.3728 cm x = 37.28 cm
