Question

Weight rather than mass be used in calculating
A)moment of inertia of a body
B) the stress in a wire due to load hanging from it
C) the binding energy of the nucleus
D) the gravitational force between the two bodies​

Answer 1

b the stress in wire due to load hanging from it

Answer 2

Answer:

B.

As the load is hanging, gravitation force acts on it.

So Weight = Mass X Gravity.

Explanation:

Why not A :

Moment if Inertia = MR^2 (M is taken here)

Why Not C :

In quantum levels, Gravitational force is negligible, so only pass is taken, moreover, the spin is enough to overcome it.

Why not D :

Gravitation force between 2 body is given by

F = GM1M2/R^2

Where G is the universal Gravitational Constant.

and M is in the equation instead of W
