NEET 2021 Physics Energy Conservation MCQ Question
A particle is released from height S from the surface of the Earth. At a certain height its kinetic energy is three times its potential energy. The height from the surface of earth and the speed of the particle at that instant are respectively :
S/4, √3gS/2
S/2, √3gS
S/2, 3√gS/2
S/4, 3√gS/2
Correct Answer
Detailed Explanation
Using energy conservation, KE = 3PE, solve for height and velocity using mgh and 1/2 mv².
