Vedclass · Answer

(B) According to Kepler's second law of planetary motion,the gravitational force exerted by the Sun on the Earth is a central force.Since the torque exerted by a central force about the center of the Sun is zero $(	au = r 	imes F = 0)$,the angular momentum $(L)$ of the Earth remains constant throughout its orbit.However,the distance between the Earth and the Sun changes in an elliptical orbit,which causes both the kinetic energy and the potential energy of the Earth to vary with its position.

The Earth revolves around the Sun in an elliptical orbit with a mean radius of $9.3 \times 10^{10} \ m$ in a period of $1$ year. Assuming that there are no outside influences,which of the following statements is true?
