Assertion: The familiar equation `mg=R` for a body on a table is true only if the body is in equilibrium.
reason: The equality of mg and `R` has no connection with the third law.

Assertion :- In equilibrium net force on the body is zero. Reason :- A body in equilibrium must be at rest.

Assertion :- In equilibrium net force on the body is zero. Reason :- A body in equilibrium must be at rest.

Assertion :- In equilibrium net force on the body is zero. Reason :- A body in equilibrium must be at rest.

Assertion:The moment of inertia of rigid body depends only on the mass of the body, its shape and size. Reason: Moment of inertia I = MR^2 where M is the mass of the body and R is the radius vector.

Assertion : Zeroth law can also be termed as law of thermal equilibrium. Reason : Two objects in thermal equilibrium with the third one, are in thermal equilibrium with each other.

A body of mass m is placed on a table. The earth is pulling the body with a force mg. Taking this force to be the action what is the reaction?
