Answer:
B) 4/5
Explanation:
The magnitude of the electric force between the two spheres is given by
where
k is the Coulombs' constant
q1 and q2 are the charges on the two spheres
r is the distance between the two spheres
Initially, we have
So the force is
Later, the two spheres are brought together so they are in contact: this means that the total charge will redistribute equally on the two spheres (because they are identical).
The total charge is
So each sphere will have a charge of
So, the new force will be
And so the ratio of the two forces is
