Answer to Question #301984 in Electricity and Magnetism for asdfg

Question

Two charges lie on positive x-axis. Charge A (2.0 x 10-9 C) is 4.0 cm from the origin and Charge B is 8.0 cm from the origin. (-3.0 x 10-9 C). What is the total force exerted by these two charges on Charge C (5.0 x 10-9 C) located at the origin?Solve for ForceBonC.

Answer 1

$F=kq_C(\frac{q_A}{r_A^2}-\frac{q_B}{r_B^2})=35~\mu N.$
