A tank containing water is placed on a spring balance. A stone of weight w is hung and lowered into the water without touching the sides and the bottom of the tank. Explain how the reading will change.

There is more water in a beaker placed in the pan of a spring balance.If we dip our finger in this water without touching the bottom of the beaker, then what would be the effect on the reading of the balance ?

A pan balance has a container of water with an overflow spout on the right hand pan as shown it is full of water right up to the overflow spout A container on the left hand pan is positioned to catch any water that overflow the entire apparatus is adjusted so that it's balanced A brass weight on the end of a string is then lowered into the water but not allowed to rest on the bottom of the container what happens next?

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 beaker containing water is placed on the platform of a spring balance. The balance reads 1.5 kg. A stone of mass 0.5 kg and density 10^(4) kg//m^(3) is immersed in water without touching the walls of the beaker. What will be the balance reading now?

A bucket of water is suspended from a spring balance. What happens to reading of balance (a) when a piece of stone suspended from a string is immersed in the water without touching the bucket (b) when a piece of lead or cork is put in the water in the bucket.

A tank containing water has an orifice in one vertical side. If the centre of orifice is 4.9 m below the surface level in the tank, the velocity of discharge is:

A water tank is 20 m deep . If the water barometer reads 10 m at the surface , then what is the pressure at the bottom of the tank in atmosphere ?

A beaker containing water is placed on the platform of a spring balance.The balance reads 15N .A stone of mass 0.5 kg and density 500 (kg)/m^(3) is kept fully immersed in water without touching walls of beaker and held at rest.What will be the balance reading now? (g=10m/s^(2))
