MCQ
Equal charges are given to two spheres of different radii. The potential will
- ✓Be more on the smaller sphere
- BBe more on the bigger sphere
- CBe equal on both the spheres
- DDepend on the nature of the materials of the spheres
✓
Answer
Correct option: A.
Be more on the smaller sphere
a
(a) $V = \frac{{kq}}{R}$ i.e. $V \propto \frac{1}{R}$
Potential on smaller sphere will be more.
(a) $V = \frac{{kq}}{R}$ i.e. $V \propto \frac{1}{R}$
Potential on smaller sphere will be more.
