Two rings having masses M and 2M, respectively, having same radius are placed coaxially as shown in figure.
If the mass distribution on both the rings is non-uniform, the gravitational potential at point P is
If the mass distribution on both the rings is non-uniform, the gravitational potential at point P is
- \(-\frac{G M}{R}\left[\frac{1}{\sqrt{2}}+\frac{2}{\sqrt{5}}\right]\)
- \(-\frac{G M}{R}\left[1+\frac{2}{2}\right]\)
- zero
- cannot be determined from given information
Answer
(A) - G M R [ 1 2 + 2 5 ]
