Pick out the wrong statement from the following

Options

A. a)The Sl unit of universal gravitational constant is `Nmkg ^(-2 )`
B. b)The gravitational force is a conservative force
C. c)The force of attraction due to a hollow spherical shell of uniform density on a point mass inside it is zero
D. d)Gravitational potential energy `= ("gravitation potential")/("mass of the body")`

Answer

C

Explanation

Option (e) is wrong statement, because
`U =- ( GM _(0) m )/(r)`
`(because V =- (GM)/(r)where V = gravitational potential)
So, U =gravitational potential Xmass of the body Therefore, the right statement is Gravitational potential energy = gravitational potential x mass of the body
