Explanation of Solution

Introduction:

The total relativistic energy of a particle is the sum of its kinetic energy and rest energy. The mass of particle is m and it is moving with velocity u with is very less than speed of light.

Write expression for total energy of the particle.

  E=K+mc2

Here, K is kinetic energy or particle and mc2 is rest energy of particle.

Substitute 12mv2 for K in above expression.

  E=12mv2+mc2

Conclusion:

The total energy of particle is mc2+12mv2 . Thus, option (a) is correct.

The total energy is the sum of kinetic energy and rest energy. Thus, option (b) is incorrect.

The cmu does not indicates any type of energy. Thus, option (c) is incorrect.

The total energy is sum of kinetic energy and rest energy. Thus, option (d) is incorrect.

The 12cmu does not indicates any type of energy. Thus, option (e) is incorrect.
