A particle of mass m moving with horizontal speed 6 m//s as shown in the figure. If m lt lt M then for one - dimensional elastic collision , the speed of lighter particle after collision will be

A particle of mass m moving in the x direction with speed 2v is hit by particle of mass 2m moving in the y direction with speed v. If the collision is perfectly inelastic, the percentage loss in the energy during the collision is close to:

The de Broglie wave length associated with a particle of mass 1 mg moving with a velocity of 1m/sec is

A particle of mass 2 kg moving with a speed of 6 m/s collides elastically with another particle of mass 4 kg travelling in same direction with a speed of 2m/s. The maximum possible deflection of the 2 kg particle is

A particle of mass 1 kg is moving alogn the line y=x+2 with speed 2m//sec . The magnitude of angular momentum of the particle about the origin is
