NEET Solved Paper 2018 Question 39

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 [NEET - 2018]

Options:

A) $ {K_B}\text{}{K_A}\text{}{K_C} $

B) $ {K_A}\text{}{K_B}\text{}{K_C} $

C) $ {K_A}\text{}{K_B}\text{}{K_C} $

D) $ {K_B}\text{}{K_A}\text{}{K_C} $

Show Answer

Answer:

Correct Answer: B

Solution:

Point A is perihelion and C is aphelion. So,

$ {V_A}\text{}{V_B}\text{}{V_C} $ So, $ {K_A}\text{}{K_B}\text{}{K_C} $
