Physics-Uniform Circular Motion
NEET Physics Uniform Circular Motion MCQ Question
Type: MCQ-diagram based-Hard-Class 11
Consider an object moving in a circle of radius R with uniform speed v. If a point P on the circle is shown such that the velocity vector is tangential to the circle at P and the acceleration vector is directed towards the center of the circle, which of the following correctly describes the relationship between v, R, and the centripetal acceleration a_c at point P?
A
a_c = v^2 / R and is directed towards the center.
B
a_c = R / v^2 and is directed away from the center.
C
a_c = v^2 * R and is directed tangentially.
D
a_c = v / R and is directed towards the center.
Correct Answer
Option A
Detailed Explanation
In uniform circular motion, the centripetal acceleration a_c is given by v^2/R and is directed towards the center, as per NCERT context.
