Non-Uniform Circular Motion – Rankers Physics

Non Uniform Circular Motion: Practice Problem & Solution

Assertion (A): In non-uniform circular motion, linear speed of the body is variable. Reason (R): In non-uniform circular motion, acceleration of the body is towards the centre.  
Both (A) & (R) are true and the (R) is the correct explanation of the (A)
Both (A) & (R) are true but the (R) is not the correct explanation of the (A)
(A) is true but (R) is false
Both (A) and (R) are false

Short Solution (Best for NEET):

To solve this problem, we apply the core principles of Non Uniform Circular Motion. Understanding the underlying formula is key to arriving at the correct answer below:

In non-uniform circular motion, linear speed is variable, so (A) is true. The net acceleration has both radial (centripetal) and tangential components, so it's not solely towards the center. Thus, (R) is false.

1. Assertion (A): A bob of mass \( m \) is freely suspended from a light rod of length \( L \). The minimum speed given to bob at lowest position to complete vertical circle is \( 2\sqrt{gL} \). Reason (R): A bob of mass \( m \) is freely suspended from a light string of length \( L \). If bob is given speed \( \sqrt{6gL} \) at the lower position then bob will be complete vertical circle.
