A spring balance measures mass of a block as 50kg when the block is submerged in water its reading is 45kg while when block is submerged in unknown liquid reading is 42kg .The specific gravity of liquid 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 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.

A matallic block weighs 15N in air. It weights 12N when immersed in water and 13 N when immersed in another liquid. What is the specific gravity of the liquid?

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 iin air is 60 N the reading is changed to 40 N when the block is submerged in water. Find the relative density of the block.

A spring balance reads 10kg when a bucket of water is suspened from it . What will be the reading of the balance when an iron piece of mass 7.2 kg suspended by a string is immersed with half its volume inside the water in the bucket? Relative density of iron is 7.2

A vessel filled with water is kept on a weighing pan and the scale adjusted of zero. A block of mass M and density rho is suspended by a masselss spring of spring constant k. This block is submerged inside into the water in the vessel. What is the reading of the scale /
