Two objects have charges 2.0 c and 1.0 c. if the objects are placed 2 meters apart, what is the magnitude of the force that the 2 c object exerts on the 1 c obejct?

Explanation:

The electric force between two charged objects is given by:

where:

k is the Coulomb's constant

q1 and q2 are the charges of the two objects

r is their separation

In this problem:

q1 = 2.0 C

q2 = 1.0 C

r = 2 m

So, the electric force is

i guess it’s a and b
