Question

Einstein's mass - energy conversion relation $E=m{c}^2$ is illustrated by :

• A. Nuclear fission
• B. Nuclear fusion
• C. Rocket propulsion
• D. Steam engine

Answer 1

Answer: (A), (B)

The correct options are
A Nuclear fission
B Nuclear fusion

Einstein's mass - energy conversion relation is demonstrated in the nuclear reactions where some mass is converted to energy.

This includes Nuclear fission and Nuclear fusion reaction.

So Option A and B are correct.

Option C and D are essentially chemical processes and do not involve nuclear reactions.
