Kinematics of Circular Motion
PHXI04:MOTION IN A PLANE

361917 Assertion :
Two similar trains are moving along the equatorial line with the same speed but in opposite directions. They will exert equal pressure on the rails.
Reason :
In a uniform circular motion, the magnitude of acceleration remains constant but the direction continuously changes.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
PHXI04:MOTION IN A PLANE

361918 When a body moves with a constant speed along a circle

1 No work is done on it
2 No acceleration is produced in the body
3 No force acts on the body
4 Its velocity remains constant
PHXI04:MOTION IN A PLANE

361919 A particle moves counter-clockwise along the circular path shown. As it moves along the path its acceleration vector continuously points toward point \(S\). The object:
