STANDARD Physics Kepler's Laws MCQ Question
Type: MCQ-conceptual-Medium-Class 11
Figure shows elliptical orbit of a planet P about the sun S. The shaded area SCD is twice the shaded area SAB. If t₁ is the time for the planet to move from C to D and t₂ is the time to move from A to B, then
A
t₁ = t₂
B
t₁ = 2t₂
C
t₁ = 4t₂
D
t₁ > t₂
Correct Answer
Option B
Detailed Explanation
According to Kepler's second law, equal areas are swept in equal intervals of time. As area SCD = 2(area SAB), hence t₁ = 2t₂.
