Question

Two uniform rods of equal length but different masses are rigidly joined to form an L-shaped body, which is then pivoted as shown. If in equilibrium the body is in the shown configuration, ratio `(M)/(m)` will be

A. `sqrt(2)`
B. 2
C. `sqrt(3)`
D. 3

Answer 1

Correct Answer - B
The person will be able to catch the ball if the horizontal component of the velocity of the ball is equal to the speed of person
`therefore " "ucos theta =(u)/(2)`
`cos theta =(1)/(2)`
`theta = 60^(@)`
