A solid cylinder rolls up an inclined plane of inclination theta with an initial velocity v . How far does the cylinder go up the plane ?

The length of a current-carrying cylindrical conductor is l, its area of cross-section is A, the number density of free electrons in it is n, and the drift velocity of electrons in it is v_d . The number of electrons passing through a particular cross-section of the conductor per unit time is given by:

Velocity of the centre of a small cylinder is v . There is no slipping anywhere. The velocity of the centre of the larger cylinder is

A tank of height H and base area A is half filled with water and there is a small orifice at the bottom and there is a heavy solid cylinder having base area (A)/(3) and height of the cylinder is same as that of the tak. The water is flowing out of the orifice. Here cylinder is put into the tank to increase the speed of water flowing out. After long time, when the height of water inside the tank again becomes equal to (H)/(2) , the solid cylinder is taken out. then the velocity of liquid flowing out of the orifice (just after removing the cylinder) will be
