The readings of the spring balance will be :

A cubical block (side l ) is in equilibrium at the interface of two liquids A and B. The spring balance reads W Newton. If the block is weighted in air, the reading of the spring balance will be :

A spring balance is attached to the ceiling of a lift. A man hangs his bag on the spring and the spring reads 49 N, when the lift is stationary. If the lift moves downward with an acceleration of 5 m//s^(2) , the reading of the spring balance will be :

A man of mass 60 kg is standing on a spring balance inside a lift. If the lift falls downwards, then the reading of the spring balance will be:-

As shown in the figure, two equal masses each of 2kg are suspended from a spring balance. The reading of the spring balance will be.

The reading in the spring balance is

The reading in the spring balance is:

The reading in the spring balance is:

The reading in the spring balance is

A body of mass 2 kg is hung on a spring balance mounted vertically in a lift. If the lift descends with an acceleration equal to the acceleration due to gravity ‘ g ’, the reading on the spring balance will be
