JEE Main Physics question
Statement 1: Comets move around the sun in elliptical orbits. The gravitational force on the comet due to the sun is not normal to the comet's velocity, but the work done by the gravitational force over every complete orbit of the comet is zero. Statement 2: Gravitational force is a non-conservative force.
Answer: (C)
Solution
Statement 1 is true — even though the gravitational force is not always perpendicular to the velocity, the work done over one complete
