The kinetic energies of a planet in an elliptical orbit about the Sun, at positions A, B and C are KA , KB and KC 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

Question

The kinetic energies of a planet in an elliptical orbit about the Sun, at positions A, B and C are KA , KB and KC 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 (A) KB > KA > KC (B) KA < KB < KC (C) KB < KA < KC (D) KA > KB > KC

Q. 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. $A C$ is the major axis and $SB$ is perpendicular to $A C$ at the position of the Sun $S$ as shown in the figure. Then

$K_{B} > K_{A} > K_{C}$

$K_{A} < K_{B} < K_{C}$

$K_{B} < K_{A} < K_{C}$

$K_{A} > K_{B} > K_{C}$

Point $A$ is perihelion and $C$ is aphelion.
So , $V_{A} > V_{B} > V_{C}$
So, $K_{A} > K_{B} > K_{C}$
