20 N

Explanation:

upthrust = 60 - 40 = 20

Answer 2

$\huge \sf \fcolorbox{red}{pink}{Solution :)}$

When a body is immersed in a liquid, the liquid exerts an upward force on the body. This force is called the upthrust or buoyant force

Given ,

The weight of body in air = 60 N

The weight of body in water = 40 N

Thus ,

The upthrust on body is (60 - 40) N i.e 20 Newton
