Question

If the earth loses its gravity, then for a body ___________

(a) Weight becomes zero

(b) Mass becomes zero

(c) Neither mass nor weight is zero

(d) Both mass and weight are zero

The question was posed to me in an internship interview.

My question is from Orbital Velocity in chapter Kinetic Theory of Gases of Engineering Physics I

Answer 1

The correct choice is (a) Weight becomes zero

The explanation: Weight = mg

As g becomes zero, weight is zero. Mass is the quantity of matter which is independent of g.
