none of these
✅ The correct answer is option C.
When a particle moves along a straight path, there will be centripetal acceleration as well as tangential acceleration.
Correct
Incorrect
✅ The correct answer is option B.
According to parallel axis theorem, the moment of inertia of a section about an axis parallel to the axis through centre 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
