Five metallic plates each of area A and separated from adjacent plate by a distance d as shown in figure. The capacitance of the system across A and B is:

A proton moving with velocity v along the axis approaches a circular current carrying loop as shown in figure. The magnitude of magnetic force on proton at this instant is

In the circuit shown in figure, what is the value of I₀ just after pressing the key K?

The kinetic energy of a body decreases by 36%. The decrease in linear momentum is

A particle of mass m is dropped from rest from a height h0 on a horizontal floor. The coefficient of restitution between the floor and particle is e. Maximum height attained by the particle after second collision is
