A simple pendulum, made of a string of length λ and a bob of mass m, is released from a small angle θ 0 . It strikes a block of mass M, kept on a horizontal surface at its lowest point of oscillations, elastically. It bounces back and goes up to an angle θ 1 . Then M is given by :
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
D
u = 
.......(i)
v = velocity of ball after collision
v = 
Since ball rises up to angle θ 1
....(ii)
from (i) & (ii)
⇒ 
⇒ M = 
m
