The kinetic energies of a planet in an elliptical orbit about the Sun, at positions A, B and C are $K_A$, $K_B

Question

The kinetic energies of a planet in an elliptical orbit about the Sun, at positions A, B and C are $K_A$, $K_B$ and $K_C$, 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

Accepted Answer

Point A is perihelion and C is aphelion. The velocity at perihelion is maximum and at aphelion is minimum. So, $V_A > V_B > V_C$, which implies $K_A > K_B > K_C$.
