Question

If both the magnitude of two charges and distance between them is doubled, then new electrostatic force (if the original force is F) between them will be​

Answer 1

Electrostatic force is directly related to the charge of each object. So if the charge of both objects is doubled, then the force will become four times greater. Four times 0.080 N is 0.320 N.

Answer 2

Answer: The new force between them will be F.

Explanation:

Let two particles be of charges be q₁ and q₂.

Now, the electrostatic force between them will be given by:

F = k .$\frac{q_1 q_2}{r^2}$ -------------------------------(1)

Where r is the distance between the particles and k is the Coulomb constant.

Now, if

r => 2r

q₁ => 2q₁

and q₂ =>2q₂

putting the new values in equation 1 we get :

F' = K.  $\frac{2q_1 2q_2}{(2r)^2}$

Where F' is the new force between the particles.

F' =  k .$\frac{q_1 q_2}{r^2}$ = F.

Thus, the new force between them will be F (i.e the new force is the same as the previously given force).
