Question

Force between two identical spheres charged with same charge if f if 50% charge of one sphere is transferred to second sphere then new force will be

Answer 1

Answer:

The new force will be $F'=\dfrac{3}{4}F$.

Explanation:

Let two charges are placed at a separation r.

Force between two identical spheres charged with same charge if F.

The force between the sphere is

$F=\dfrac{kq^2}{r^2}$

If  50% of the charge of one sphere is transferred to second sphere then,

The new force between the two sphere becomes

$F'=\dfrac{\dfrac{q}{2}\times\dfrac{3q}{2}}{d^2}$

$F'=\dfrac{3}{4}k\dfrac{kq^2}{d^2}$

$F'=\dfrac{3}{4}F$

Hence, The new force will be $F'=\dfrac{3}{4}F$.
