Question

what is relatiove density ?study the given diagram and calculate the pressur exerted by water at the bottom of the tank .the density of water is 1000kg/m²​

Answer 1

Relative Density (R.D) is a ratio of density of the substance to the density of water. It has no S.I units because it's just a ratio.

Given,

Pressure = Height*Acceleration due to gravity*Density of water

= h*9.8*1000 Pa

= 9800h Pa

[Height is not given in the question, if you know, please multiply it with 9800 and you'll get the pressure]

I hope this helps.
