Explanation:


Electric Potential Difference

The electric potential difference between two points in an electric field is defined as the work done per unit charge in moving a positive test charge from one point to the other against the electric field.

Formula for Electric Potential Difference

The formula for electric potential difference is given by:
V = W/Q

where V is the electric potential difference, W is the work done, and Q is the charge.

Applying the Formula

In this problem, we are given two concentric conducting spheres of radii R and 2R carrying charges Q and -2Q respectively. The charge on the inner sphere is doubled. We need to find the potential difference between the two spheres.

We can start by using the formula for electric potential difference:
V = W/Q

The work done in moving a charge from one sphere to the other is given by:
W = Q1V1 - Q2V2

where Q1 and Q2 are the charges on the spheres and V1 and V2 are their respective potentials.

Initially, the potential of the outer sphere is zero and the potential of the inner sphere is given by:
V1 = kQ/R

where k is the Coulomb constant.

The potential of the outer sphere after the charge on the inner sphere is doubled is given by:
V2 = k(-2Q)/(2R) = -kQ/R

Substituting the values in the formula for work done, we get:
W = Q(2kQ/R + kQ/R) = 3kQ^2/R

The potential difference is then given by:
V = W/Q = 3kQ/R

Final Answer

Therefore, the potential difference between the two spheres will be 3kQ/R.
