Answer:
4 m/
Explanation:
From Equilibrium of forces, The Tension in string is cancelled by the Weight (product of mass and acceleration due to gravity) of the body acting downwards.
The Net force = Mass * Acceleration.
Since Net Force = 20 Newton, Mass = 5kg, therefore;
20 = 5kg * acceleration. Dividing the RHS and LHS of the equation by 5, we have;
Acceleration = which gives 4.
Note: RHS means Right Hand Side.
LHS means Left Hand Side.

Okay, haven't done physics in years, let's see if I remember this.
So Coulomb's Law states that
so if we double the charge on 
and double the distance to 
we plug these into the equation to find

So we see the new force is exactly 1/2 of the old force so your answer should be
if I can remember my physics correctly.
