Question

As an $\alpha$-particle approaches a ${}_7^{14}\text{N}$ nucleus, the potential energy :

• A. increases as it approaches the nucleus
• B. attains maximum value as inter nuclear distance is approached
• C. reaches to a minimum at the time of fusion
• D. all of the above

Answer 1

The correct option is D all of the above

From figure it can be seen that, due to repulsion of alpha from nucleus, potential energy varies
