NEET Physics (general) MCQ Question
Type: MCQ-conceptual-Easy-Class 11
Which of the following statements about the net force acting on a particle moving in a circular path is correct?
A
The net force is equivalent to the tension in the string if the particle is moving at a constant speed.
B
The net force acting on the particle is zero when it moves in a circle at constant speed.
C
The net force can be calculated by the formula T = mv^2/l, where T is tension, m is mass, v is speed, and l is length.
D
The net force always acts in the direction of the particle's velocity in circular motion.
Correct Answer
Option A
Detailed Explanation
When a particle moves in a circle, the net force acting on it is the tension in the string, directed towards the center of the circle, as per the laws of motion principles outlined in the context.
