CBSEENPH11018153

A liquid exerts a buoyant force of 2.4 kg on a body of mass 6.4 kg when it is immersed in the liquid. What is the apparent weight of the body in the liquid?

Solution
Buoyant force exerted by the liquid = 2.4 kg
Mass of the body when immersed in liquid, m = 6.4 kg 

Therefore,

Apparent weight of the body in the liquid is given by, = 6.4 –2.4 = 4 kg.
