Question

The kinetic energies of a planet in an elliptical orbit about the Sun, at positions A, B and C are KAK_A, KBK_B and KCK_C, respectively. AC is the major axis and SB is perpendicular to AC at the position of the Sun S as shown in the figure. Then

1

KB<KA<KCK_B < K_A < K_C

2

KA>KB>KCK_A > K_B > K_C

3

KA<KB<KCK_A < K_B < K_C

4

KB>KA>KCK_B > K_A > K_C

Step-by-Step Solution

Point A is perihelion and C is aphelion. The velocity at perihelion is maximum and at aphelion is minimum. So, VA>VB>VCV_A > V_B > V_C, which implies KA>KB>KCK_A > K_B > K_C.

Exam Context & Concepts Covered
