If A Body Is Rolling On The Surface Its Total Physics Question

If a body is rolling on the surface, its total energy will be

Options

(a)(1/2) mv² – (Gm₁m₂/R)
(b) (1/2) mv² + (1/2) Iω²
(c) (1/2) mv² – (1/2) mR²ω²
(d) None

Correct Answer:

(1/2) mv² + (1/2) Iω²

Explanation:

Total energy = P.E. + K.E. of (linear motion + Rotation)
= 0 + (1/2) mv² + (1/2) Iω²
Total energy = (1/2) mv² + (1/2) Iω².
