Acharge of 7.0 μc is to be split into two parts that are then separated by 9.0 mm. what is the maximum possible magnitude of the electrostatic force between those two parts?

Explanation:

As we know that a charge is split into two parts

so we have

now we have

here we know

here we have

r = 9 mm

now to obtain the maximum value of the force between two charges

so we have

so we have

so the maximum force is given as

mass and volume are the answers you are looking for

c. magnitude and direction
