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 some water in a beaker placed on the pan of 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.

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 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 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:
