Question

What happens to the force between two charges if one of the charges are doubled?

it decreased by a quarter
it quadruples
it doubles
it cuts in half

Answer 1

The new force between the charges becomes double of the initial force.

Step-by-step explanation:

The force acting between charge particles is given by :

`F=k(q_1q_2)/(r^2)`

k is electrostatic constant

r is distance between charges

If one of the charges are doubled, then, q₁ = 2q₁

The new force becomes,

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

So, the new force between the charges becomes double of the initial force.
