STANDARD Physics Conservation of Angular Momentum MCQ Question
Type: MCQ-conceptual-Medium-Class 11
A planet orbits the sun in an elliptical path as shown in Perihelion the figure. Let v_P and v_A be speed of the planet when at perihelion and aphelion respectively. Which of the following relations is correct?
A
r_A / r_P = v_A / v_P
B
r_P / r_A = v_P / v_A
C
r_P / r_A = v_A / v_P
D
r_A / r_P = v_P / v_A
Correct Answer
Option C
Detailed Explanation
According to the law of conservation of angular momentum, L_P = L_A, leading to r_P / r_A = v_A / v_P.
