A. 3.3 * 10-8 coulombs

B. 3.6 * 10-6 coulombs

C. 4.8 * 10-8 coulombs

D. 6.0 * 10-8 coulombs

E. 3.3 * 10-3 coulombs

We use the equation expressed as:

F = k*Q*q / (r^2)

where k is equal to 9.0 * 109 newton·meter2/coulombs2, Q is the charge of one particle, q is the charge of the other particle and r is the distance between them.

3.0 * 10^-3 = 9.0 * 10^9 (3.3 * 10-8 coulombs) q / (6.0 * 10-2) ²

q = 3.3 * 10-8 coulombs
