Two balls of masses 4m and 8m are in motion with velocities 2v and v respectively. The ratio of their momentum would be :
- 2 : 1
- 1 : 2
- 1 : 1
- 1 : 4

A body of mass m moving with a velocity v is acted upon by a force. Write expression for change in momentum in each of the following cases (i) when v << c (ii) when v → c, and (iii) when v << c but m does not remain constant. Here c is the speed of light.
