Detailed Solution

Gravitational force and buoyant force are the forces acting on an object in the downwad and upward direction respectively, while it is immersed in a liquid.
Buoyant force:
The buoyant force is the ascending force exerted on an object entirely or partly immersed in a liquid. This ascending force is also called Upthrust. Question Image

Gravitational force:
The attractive force applied by the earth on all the objects in the universe is gravitational force.

F = \frac{G (m_{1} m_{2})}{r^{2}} (where G = Gravitational constant,

F = force

G = gravitational constant

m_{1} = mass of object 1

m_{2} = mass of object 2

r = distance between centers of the masses)

Gravitational and buoyant are the forces acting on an object while immersed in liquid.
When a body is immersed in a liquid, it is pulled towards the ground due to the gravitational pull.
Also when the object is immersed in liquid an amount of liquid equal to the volume of the immersed object is displaced and there is an ascending force exerted on the object that is entirely or partly immersed in the liquid. This ascending force is also called Upthrust or Buoyant force.
