Statement-1 : A thin uniform rod is undergoing fixed axis rotation about one its end with variable angular accleration. Then acceleration vector of any two moving point on the can not be parallel at an instant of time.
Statement-2: for a rod undergoing fixed axis rotation, the velocity of any two moving points on the rod at different distances from centre of rotation are different.

A

Statement-1 is true, Statement-2: is true, Statement-2 is a correct explanation for Statement-1.

B

Statement-1 is true, Statement-2: is true, Statement-2 is NOT a correct explanation for Statement-1.

C

Statement-1 is true but statement-2 is false

D

Both statement 1 false and statement 2 are true.

Text Solution

Verified by Experts

The correct Answer is:
D
Since the angular speed and angular acceleration of each moving point on the rod is same, acceleration of each moving point on the rod is in same direction, that is, parallel. Hence statement-1 is false
