Question

What will happen to the force felt between two charged objects if the distance between them is 1/3rd of the original distance

Answer 1

New force = 9(initial force)

Step-by-step explanation:

The force between two charges is given by :

`F=(kq_1q_2)/(r^2)`

Where

d is the original distance

Let d' is the new distance such that, r' = r/3

New force,

`F'=(kq_1q_2)/(r'^2)\\\\F'=(kq_1q_2)/(((r)/(3))^2)\\\\F'=9* (kq_1q_2)/(r^2)\\\\F'=9F`

So, the new force becomes 9 times the initial force.
