Physics · NEET · NTA Exams — Rotational motion
If two circular discs of the same weight and thickness are made from metal of different densities, d1 and d2 (d1 > d2). Their moment of inertia are \(A_{1}\) and \(1_{2}\). Then, \(I_{1} / I_{2}\) equals
- \(\frac{d_{1}}{d_{2}}\)
- \(\frac{d_{2}}{d_{1}}\)
- \(\frac{2 d_{1}}{d_{2}}\)
- \(\frac{2 d_{2}}{d_{1}}\)
Answer
(B) d_ 2 d_ 1
