Question

The weight of a piece of a stone when fully immersed in water is 18n and it dispaces 4n of water what is the wieght of the stone in air

Answer 1

Answer:

Given

weight of stone in water = 18 N

weight of water it displaced = 4 N

we know that

when a object is immersed in water there will be a upward force acting on it which reduces it's weight

weight of stone in water =

weight of stone in air - weight of water displaced by it

weight of stone in air = 18N + 4N = 22N
