Assertion: A man in a dosed cabin falling freely does not experience gravity.
Reason: Inertial and gravitational mass have equivalence.

Answer

A

Explanation

In a closed cabin falling freely, the normal reaction on the man is zero, hence, man does not exprience gravity.
Inertial mass of a body is the ratio of net force acting on the body to the acceleration produces in the body i.e.,
`m=(F)/(a)`
Gravitational mass of a body is the ratio of gravitational force actin on the body to the acceleration due to gravity,
i.e., `m=(w)/(g)`
Inertial mass and gravitational mass are equivalent. Hence , option `(a)` is true.
