Explanation:
It is given that,
Charge on helium nucleus is 2e and its mass is
Speed of nucleus at A is
Potential at point A,
Potential at point B,
We need to find the speed at point B on the circle. It is based on the concept of conservation of energy such that :
increase in kinetic energy = increase in potential×charge
So, the speed at point B is .
