Question

EXER
1. A particle revolves round a circular path with a constant
speed
(i) The velocity of the particle is along the tangent.
(ii) The acceleration of the particle is always towards
center
(iii) The magnitude of acceleration is constant.
(iv) The work done by the centripetal force is always
zero.
(1) (i). (ii)
(2) (i), (ii), (iii)
(3) (ii), (iii), (iv) 4) All options are correct
2. A particle of mass m moves in a circle of radius R with
uniform speed v
(1) The angular speed of particle is v/R.​

Answer 1

Answer:

4All are correct

Explanation:All are corect

linear velocity is along tanget

angle b/t velocity and centripetal force is 90 s therefore w=0
