Solution

The correct option is A $0 N$
There is no extension or compression in the spring because one end is free. Hence, spring force is 0N.

A spring of spring constant 2 N/m is attached to a mass of 1kg at one end and free at other end. The system is allowed to free fall with the block below the spring. The tension force in the spring is(Use g=10m/s2)

The correct option is A 0NThere is no extension or compression in the spring because one end is free. Hence, spring force is 0N.
