A 2kg block is dropped from a height of 0.4 m on a spring of force constant 
. The maximum compression of the spring is
Text Solution
Verified by ExpertsThe correct answer is:
A
: When a block is dropped from a height, its potential energy gets converted into kinetic energy and finally spring get compressed due to this energy.
∴ ∴ Gravitational potential energy of block = Elastic potential energy of spring
⇒ ⇒ 
⇒ ⇒ 
.
