Question

Consider the following statements.
1. The strongest force in nature is the strong nuclear force.
2. Atomic power plant works on the principle of fission.
3. Cadmium is not a radioactive element.
4. Einstein's mass-energy relation is given by the expression E = m$c^2$
Which of the statements given above are correct?

• A. 1, 2 and 3
• B. 2, 3 and 4
• C. 1, 2 and 4
• D. 1, 2, 3 and 4

Answer 1

Answer: (D)

1, 2, 3 and 4

Gravity is the weakest force whereas nuclear force is the strongest force.
In fission, huge amount of energy is released which is further used for various purpose such as making nuclear weapons. Atomic power plant works on the principle of fission.
Cadmium is not a radioactive element.
Mass-energy relation $E=m{c}^2$ is given by Albert Einstein.
All the above given statements are true, thus option D is correct.
