A) earths surface
B) a height \[{{R}_{e}}\] from earths surface (\[{{R}_{e}}\] = radius of earth)
C) a point below the earths surface
D) infinity
Correct Answer: D
Solution :
Gravitational potential, \[V=-\frac{GM}{r}\] and intensity of gravitational field, \[I=\frac{GM}{{{r}^{2}}}\] If \[V=0\] and \[I=0,\] Then, \[r=\infty \] (infinity) So, the point at which the value of both gravitational potential and gravitational field is zero is at infinity.You need to login to perform this action.
