Q12 of 48 Page 38

Which of the diagrams shown in Fig. 6.6 most closely shows the variation in kinetic energy of the earth as it moves once around the sun in its elliptical orbit?

when earth is near the sun then due to gravitational pull

K.E. decreases and when earth is away from sun gravitational


pull is less as a result K.E. increases.


option(d) best represents it.
