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

Answers

  1. Answer:

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

    Explanation:

    The force acting between charge particles is given by :

    F=k\dfrac{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'=\dfrac{2kq_1q_2}{r^2}\\\\F'=2F

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