Answer:(a) 135 kV

(b) The charge chould be moved to infinity

Explanation:(a)

The potential at a distance of

rfrom a point charge,Q, is given bywhere

Difference in potential between the points is

(b)

If this potential difference is increased by a factor of 2, then the new pd = 135 kV × 2 = 270 kV. Let the distance of the new location be

x.The charge chould be moved to infinity
