Calculate the wave length of an electron of mass 9.1 xx 10^(-31) kg , moving with a velocity of 2.05 xx 10^(7)ms^(-1) .

The rest mass of an electron is 9.1 xx10^(-31) kg. Its kinetic energy when it moves with a speed of 2.4xx10^(8) m/s is

A body of mass 5 xx 10^(3) kg moving with speed 2 m/s collides with a body of mass 15 xx 10^(3) kg inelastically & sticks to it. Then loss in K.E. of the system will be :
