Two bodies A and B having masses m and 4m respectively are moving with equal linear momentum. The ratio of kinetic energies between A and B is

- 1 : 2
- 1 : 1
- 4 : 1
- 1 : 4

**Answer**

p = mv

KE = ½mv^{2} = ½p^{2}/m

KE is inversely proportional to the mass of the body.

**The correct option is C.**
