Initially spring in its natural length. Now, a block of mass 0.25 kg is released, then find out the value of maximum force by system on the floor.
Text Solution
Verified by ExpertsThe correct answer is:
C
If 
be the compression in the spring, when a block of 0.25 kg is released.
From law of conservation of energy,
Potential energy of spring 
Potential energy of block
where, 
is force constant of spring.
Force applied by the spring on the block, 
From free body diagram,
Maximum force by system on the floor,
N 
= 25 N
