Vertical Circular Motion – Tension and Velocity – Rankers Physics

Vertical Circular Motion: Practice Problem & Solution

Assertion (A): A body tied to an end of a string is whirled along a vertical circle by giving some velocity at the lowest position. If the velocity becomes zero before the tension in the string is zero, the body will leave the circular path at the position of its zero velocity and then fall vertically downward. Reason (R): In vertical circular motion, tension in the string at the highest position is maximum.
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 Vertical Circular Motion. Understanding the underlying formula is key to arriving at the correct answer below:

If velocity becomes zero before tension, the object leaves the circular path and follows a parabolic trajectory, not vertically downward. So (A) is false.

Tension is maximum at the lowest point and minimum at the highest point in vertical circular motion. So (R) is false.

1. Assertion (A): A particle is moving in a circle with constant tangential acceleration such that its speed \(v\) is increasing. Angle made by resultant acceleration of the particle with tangential acceleration increases with time. Reason (R): Tangential acceleration \(= |dv/dt|\) and centripetal acceleration \(= v^2/R\).
2. Assertion (A): On an unbanked road, as the frictional force increases, the safe velocity limit for taking a turn also increases. Reason (R): Banking of roads will increase the value of limiting velocity.
3. Assertion (A): When an automobile while going too fast around a curve overturns, its inner wheels leave the ground first. Reason (R): The inner wheels are moving in a circle of smaller radius, the maximum permissible velocity for them is less.
4. Assertion (A): In turning a vehicle safely with uniform speed in circular path friction is static in nature and towards centre. Reason (R): In turning a vehicle in circular path with increasing speed friction is kinetic in nature and tangential in direction.  
5. Assertion (A): If a body is in state of uniform circular motion then its velocity and acceleration both are varying. Reason (R): If magnitude of velocity is \(v\) and radius of uniform circular motion is \(r\) then magnitude of acceleration is \(v^2/r\).
