Question

the force between two charge is 15 F . If both the charges and distance between them is doubled then new electrostatic force will be ​

Answer 1

Answer:

Explanation:

As the force is inversely proportional to distance^2

so if distance is doubled then force is 1/4 times

so new force= 15F/ 4 = 3.75 F
