Question

A planet revolves around the sun in an elliptical orbit. The linear speed of the planet will be maximum at

• A. D
• B. B
• C. A
• D. C

Hint:

Closest to Sun = Fastest; Farthest from Sun = Slowest.

Answer 1

The Correct Option is C

Step 1: Kepler's Second Law
According to the Law of Conservation of Angular Momentum, $mvr$ is constant.
Step 2: Speed-Distance Relationship
Speed ($v$) is inversely proportional to the distance ($r$) from the Sun.
Step 3: Analysis
Distance is minimum at point A (Perihelion), so the linear speed is maximum at that point.
Final Answer: (c)
