A) \[\frac{U}{{{r}^{2}}}\]
B) \[\frac{U}{r}\]
C) \[Ur\]
D) \[U{{r}^{2}}\]
Correct Answer: B
Solution :
Weight of a body depends upon acceleration due to gravity (g). It is given by W = mg ... (i) Also, gravitational potential energy U = mgr ... (ii) From Eqs. (i) and (ii), we get \[W=mg=\frac{U}{r}\]You need to login to perform this action.
