हिन्दीGiven below are two statements: Statement I: In pure translational motion, all particles of a rigid body have the same velocity at any given instant. Statement II: When a cylinder rolls without slipping down an inclined plane, the point of contact with the plane has a non-zero velocity directed down the incline. In the light of the above statements, choose the most appropriate answer from the options given below:
Correct answer · Option 3
Statement I is correct but Statement II is incorrect.
Explanation
Statement I is correct. Statement II is incorrect because for rolling without slipping, the instantaneous velocity of the contact point is zero.
