Question

-27 A particle is moving with uniform speed in a circle
of radius 2m in with centre at origin in clockwise
direction. If its velocity at an instant is (21+4)
m/s, then its acceleration at that instant will be
(1) (81-61) m/s2
(2) (-4/5 i +25 ſ) m/s2
(3) (4.51-25) m/s2
(4) (-81 +61) m/s​

Answer 1
