A mass of 
falls from a height of 
and lands on a mass less platform supported by a spring having spring constant 
as shown in the figure. The maximum compression of the spring is. (acceleration due to gravity 
)
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
Let 
be the maximum compression. Now, potential energy gain by spring 
Potential energy loss by mass of 
-ve value of ' x ' means spring moves upward, so it is impossible. So
