SATHEE: Kinematics Question 533

Kinematics Question 533

Question: A sphere it’s suspended by a thread of length $l$ . What minimum horizontal velocity has to be imparted the ball for it to reach the height of the suspension[ it’sM Dhanbad 1994]

Options:

A) $g l$

B) $2 g l$

C) $\sqrt{g l}$

D) $\sqrt{2 g l}$

Show Answer

Answer:

Correct Answer: D

Solution:

Kinetic energy given to a sphere at lowest point = potential energy at the height of suspension therefore $\frac{1}{2} m v^{2} = m g l$ $v = \sqrt{2 g l}$
