NEET Physics Work, Energy, and Power Spring Energy MCQs

Two springs A and B with spring constants $k_A$ and $k_B$ respectively ($k_A = 2k_B$) are stretched by the same force. If the energy stored in spring A is $E_A$, what is the energy stored in spring B?

A spring of natural length 'l' is fixed at one end and a block of mass 'm' is attached to its other end. The system rests on a smooth horizontal table. The block is pulled to extend the spring by an amount 'x' and then released. The total mechanical energy of the system at any instant during the oscillation, when the extension is 'y', is:

A block of mass 'm' is attached to two identical springs with spring constant 'k' each, connected in parallel. The block is displaced by 'x' from its equilibrium position and released. The maximum speed of the block during its subsequent oscillation is:

A spring-mass system oscillates with a period 'T'. If the spring is cut into 'n' identical parts and one of these parts is used with the same mass, the new period of oscillation will be:

Two springs of spring constants k and 2k are connected in series. A mass m is attached to the combination. What is the time period of oscillation?

A spring with spring constant 'k' is stretched by a distance 'x'. If the spring is cut into two equal halves and the same mass is attached to one half and stretched by the same distance 'x', how does the potential energy stored in the half-spring compare to the original spring?

A spring with spring constant $k$ is compressed by a distance $x$. What is the potential energy stored in the spring?

If the spring constant of a spring is doubled, and the compression is halved, the potential energy stored in the spring will be:

The unit of spring constant is:

A spring stores 4 J of potential energy when compressed by 0.1 m. What is its spring constant?
