Answer 2

Answer:

If charge on hollow metal is Q, then we need to make it 2Q to double the overall potential

Explanation:

The formula for the electric potential due to a point charge is V=kQ / r

Here Q is the charge on the point, r is the distance and k is the constant.

In the formula, since k is a constant, so in order to double the Electrical potential we shall ne needing to double the amount of charge on the hollow metal.

If charge on hollow metal is Q, then we need to make it 2Q to double the overall potential
