A small block of mass 20 g and charge 4 mc is released on a long smooth inclined plane of inclination angle of 45^(@) A uniform horizontal magnetic field of 1 T is acting parallel to the surface as shown in the figure . The time from the start when the block loses contact with the surface of the plane is

A block of mass m is placed on an inclined plane which is moving with constant velocity v in horizontal direction as shown in figure. Then find out work done by the friction in time t if the block is at rest with respect to the incline plane.

A block of mass m and positive charge q is placed on an insulated frictionless inclined plane as shown in the figure. A uniform electric field E is applied parallel to the inclined surface such that the block is at rest. Calculate the magnitude of the electric field E.

A block of mass m is released on the top of a smooth inclined plane of length x and inclination theta as shown in figure. Horizontal surface is rough. If block comes to rest after moving a distabce d on the horizontal surface, then coefficient of friction between block and surface is :-
