The reading of spring balance when a block is suspended from it in air, is `60N` .This reading is changed to `40N` when the block is immersed "],[" in water. The specific gravity of the block is:
(1) `3`
(2) `2`
(3) `6`
(4) `3/2`

The reading of a spring balance when a block is suspended from it in air is 60 N. This reading is changed to 40 N when the block is submerged in water. The relative density of the block is:

The reading of a spring balance when a block is suspended from it in air is 60 N. This reading is changed to 40 N when the block is submerged in water. The relative density of the block is:

The reading of a spring balance when a mass is weighed on it in air is 40 gm. When the mass is immersed in water, its reading is 20 gm. The specific gravity of the mass is

A block weight 15 N in air and 12 N when immersed in water find the specific gravity gravity of block.

A block hangs from a spring balance. The balance reads 40 N in air, 35 N when block is immersed in water and 25 N when block is immersed in another liquid. Find the density of block and other liquid.

An object is suspended from a spring balance in a lift. The reading is 240 N when the lift is at rest. If the spring balance reading now change to 220N, then the lift is moving

A spring balance reads W_(1) when a ball is suspended from it. A weighing machine reads W_(2) when a tank of liquid is kept on it. When the ball is immersed in the liquid, the spring balance reads W_(3) and the weighing machine reads W_(4) . Then, which of the following are not correct?

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.

The string AB vibrates in two loops with a tuning fork when block hasngs in air. Now block is completely immersed in water, the string vibrates in three loops with same tuning fork. The specific gravity of block is :

A wire gets elongated by 4 mm when a block of mass 2 kg is suspended from it. Now, the block is immersed in water, the wire contracts by 1 mm. Find the density of block when the density of water is 1000kg//m^(3) .
