Giving reasons and state the reading on a spring balance when it is attached to a floating block of wood which weighs 50 g in air.

A mass is hanging on a spring balance which is kept in a lift. The lift ascends. The spring balance will show in its reading

A block of mass m is placed on weighing machine and it is also attached with a spring balance. The whole system is placed in a lift as shown in figure. Left is moving with constant acceleration 10 m//s^(2) in upward direction. The reading of the weighing machine is 500 N and the reading of spring balance is 300 N. Find the actual mass of the block in kg. (Takr g = 10 m//s^(2) )

An object of mass 5 kg is attached to the hook of a spring balance and the balance is suspended vertically from the roof of a lift. The reading on the spring balance when the lift is going up with an acceleration of 0.25 ms^(-2) is take, (take, g=10ms^(-2) )

A 20 N metal block is suspended by a spring balance. A beaker containing some water is placed on a weighing machine which reads 40 N . The spring balance is now lowered so that the block gets immersed in the water. The spring balance now reads 16 N . The reading of the weighing machine will be.

A body attached to a spring balance weighs 10 kg on the Earth. The body attached to the same spring balance is taken to a planet where gravity is half that of the Earth. The balance will read

Four beakers are labelled as P,Q,R and S. A student puts salt solutions of different concentrations in the four beakers without spring balance gives a reading of 150g in air. When this solid, while still suspended from the hook of spring balance, is fully immersed in beakers P,Q,R and S, the readings shown by the spring balance in the four beakers P,Q,R and S are 110g,130g, 140g and 120g respectively. The most concentrated solution is contained in the beaker labelled as:

A monkey of mass mkg slides down a light rope attached to a fixed spring balance, with an acceleration a. The reading of the spring balance is W kg. [g = acceleration due to gravity]

A weight is suspended from the ceiling of a lift by a spring balance. When the lift is stationary the spring balance reads W . If the lift suddenly falls freely under gravity, the reading on the spring balance will be
