calculate the radius of circular path on which the ball moves.

A positively charged particle of mass m and charge q is projected on a rough horizontal x-y plane surface with z- axis in the vertically upward direction. Both electric and magnetic fields are acting in the region and given by A small charged ball having mass m and charge q is suspended from a rigid [...]

There is a constant homogeneous electric field of 100Vm^−1 within the region x = 0 and x = 0.167m pointing in x-direction. There is a constant homogeneous magnetitic field B within the region x=0.167m and x = 0.334m pointing in the z-direction. A proton at rest at the origin is released in positive A small [...]

A small charged ball having mass m and charge q is suspended from a rigid support by means of an inextensible thread of length l. It is made to rotate on a horizontal circular path in a uniform, time independent magnetic field of induction B which is directed upward. The time period of revolution of [...]
