Question
Explain the following :
A ship submerges more as it sails from sea water to river water.
Advertisements
Solution
Density of river water is less than the density of sea water. Hence, according to the law of floatation, to balance the weight of the ship, a great volume of water is required to be displaced in river water having a comparitively lower density.
