A sphere is 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
A sphere is 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
$gl$
$2gl$
$\sqrt {gl} $
$\sqrt {2gl} $
A sphere is 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
Kinetic energy given to a sphere at lowest point $=$ potential energy at the height of suspension
$⇒$ $\frac{1}{2}m{v^2} = mgl$
$v = \sqrt {2gl} $
