Question

A body floats in completely immersed condition in water as shown in figure. As the whole system is allowed to slide down freely along the inclined surface, the magnitude of buoyant force

(a) remains unchanged 

(b) increases

(c) decreases

(d) insufficient data

Answer 1

Correct option (c) decreases

Explanation :

As apparent weight of the downward accelerating body decreases. So, that of water also decreases and this leads to decrease in magnitude of buoyant force.
