A 5.0-C charge is 10 m from a -2.0-C charge.The electrostatic force is on the positive charge is:

Question

Quizplus · Accepted Answer

The electrostatic force between two charges is given by Coulomb's law:

F = k(q1q2/r^2)

where F is the force, k is Coulomb's constant (9.0 x 10^9 N m^2/C^2), q1 and q2 are the charges, and r is the distance between them.

Substituting the given values, we get:

F = (9.0 x 10^9 N m^2/C^2)(5.0 C)(2.0 C)/(10 m)^2

F = 9.0 x 10^-10 N

Since the two charges have opposite signs, the force is attractive, i.e., toward the negative charge. Therefore, the answer is A.
