हिन्दीRefer to the given figure depicting a cylinder rolling without slipping down an inclined plane. At the instant shown, if the centre of mass of the cylinder \( P_1 \) is moving with a speed \( v \), what are the magnitudes of the instantaneous velocities of the contact point \( P_3 \) and the uppermost point \( P_4 \)?
Correct answer · Option 2
\( v_3 = 0 \), \( v_4 = 2v \)
Explanation
For pure rolling without slipping, the instantaneous velocity of the point of contact \( P_3 \) is zero, and the uppermost point \( P_4 \) moves with velocity \( v + \omega R = 2v \).
