Given below are two statements : one is labelled as Assertion A and the other is labelled as Reason RAssertion A: The kinetic energy needed to project a body of mass m from earth surface to infinity is $\displaystyle \frac{1}{2} \mathrm{mgR}$, where R is the radius of earth.Reason R: The maximum potential energy of a body is zero when it is projected to infinity from earth surface.In the light of the above statements, choose the correct answer from the options given below
Official answer
From NTA’s final answer key for this paper.
