According to parallel axis theorem, the moment of inertia of a section about an axis parallel to the axis through center of gravity (i.e. IP) is given by(where, A = Area of the section, IG = Moment of inertia of the section about an axis passing through its C.G., and h = Distance between C.G. and the parallel axis.)

According to parallel axis theorem, the moment of inertia of a section about an axis parallel to the axis through center of gravity (i.e. IP) is given by(where, A = Area of the section, IG = Moment of inertia of the section about an axis passing through its C.G., and h = Distance between C.G. and the parallel axis.)

IP = IG - Ah2

IP = IG + Ah2

IP = IG / Ah2

IP = Ah2 / IG

IP = IG - Ah2

IP = IG + Ah2

IP = IG / Ah2

IP = Ah2 / IG

According to Newton's first law of motion,

To every action, there is always an equal and opposite reaction

None of these

Everybody continues in its state of rest or of uniform motion, in a straight line, unless it is acted upon by some external force

The rate of change of momentum is directly proportional to the impressed force, and takes place in the same direction, in which the force acts
