Consider a cylinder of mass M = 1 kg and radius R = 1 m lying on a rough horizontal plane. It has a plank lying on its top as shown in the figure.
A force F = 35 N is applied on the plank such that the plank moves and causes the cylinder to roll. The plank always remains horizontal. There is no slipping at any point of contact.

Two identical thin rings each of radius R meters are coaxially placed at a distance R meters apart. If Q 1 coulomb and Q 2 coulomb are respectively the charges uniformly spread on the two rings, the work done by external agent in moving a charge q slowly from the center of ring with charge Q1 to that of other is,
