Question

'Weight' of a body may have the following attributes.
I. It is the gravitational force acting on a body at the earth's surface
II. It is independent of the mass of the body
III. The body feels weightlessness during free fall
IV. It is different at different places on earth's surface.

• A. I, II and III only
• B. I, III and IV only
• C. I and III only
• D. I, II, III and IV

Answer 1

The correct option is B I, III and IV only

Weight on a body is defined as the force acting on it due to gravity.

$W=mg$

Since, the value of $g$ is different at different places on the earth. Hence, weight of a body also differs at different places.

Since, in a state of free fall, there is no reaction force acting on a body, hence the body feel weightlessness in a state of free fall.

Hence, cases I, III and IV are True.
