Question

A floating ball normally weighs 5.5 N. The acceleration of gravity is 9.8 m/s 2 . What is the size of the buoyant force that acts on it?

Answer 1

5.5 N

Step-by-step explanation:

Weigh of floating ball=5.5 N

Acceleration due to gravity=9.8
`m/s^2`

We have to find the size of the buoyant force that acts on it.

We know that

Buoyant force is that force which act in upward direction and exert by fluid and opposes the weight of an immersed object.

Therefore,

Buoyant force=Weight of ball

Buoyant force=5.5 N

Hence, the size of buoyant force acts on the ball=5.5 N
