NEET Physics Uniform Circular Motion MCQ Question

Type: MCQ-diagram based-Medium-Class 11

Consider an object in uniform circular motion. Visualize a diagram where the position vectors rr and r′r' and the velocity vectors vv and v′v' are shown at points PP and P′P' respectively. If Δv\Delta v is placed on the line that bisects the angle between rr and r′r', what is the direction of Δv\Delta v with respect to the circular path?

Question diagram
A

Towards the center of the circle

B

Away from the center of the circle

C

Tangential to the circle

D

Parallel to rr

Correct Answer

Option A

Detailed Explanation

As per the NCERT context, Δv\Delta v is directed towards the center of the circle when placed on the line bisecting the angle between rr and r′r', indicating centripetal acceleration.
