AIPMT MAINS 2009 Physics Kinematics MCQ Question
Type: MCQ-conceptual-Medium-Class 11
A particle starts its motion from rest under the action of a constant force. If the distance covered in first 10 seconds is S₁ and that covered in the first 20 seconds is S₂, then:
A
S₂ = 3S₁
B
S₂ = 4S₁
C
S₂ = S₁
D
S₂ = 2S₁
Correct Answer
Option D
Detailed Explanation
The distance covered under constant acceleration is proportional to the square of the time. Therefore, S₂/S₁ = (20/10)² = 4.
