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.

When a block is suspended in air from a spring balance, it reads 60 N. When the block is immersed completely in water, the spring balance reads 40 N. The specific gravity of the block 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 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.
