What impulse need to be given to a body of mass m, released from the surface of earth along a straight tunnel passing through centre of earth, at the centre of the earth, to bring it to rest. (Mass of earth M, radius or earth R)
- \(m \sqrt{\frac{G M}{R}}\)
- \(\sqrt{\frac{G M n}{R}}\)
- \(m \sqrt{\frac{G M}{2 R}}\)
- zero
Answer
(A) m G M R
