Question

qstn) A partiue is moving with a unifrom speed, U in a cricular path radius R, the anguler speed of the particle W = A)ur B)u devided r C) r devided u D) u2 devided r​

Answer 1

Answer:

The particle has only centripetal acceleration and no tangential acceleration

since it is moving with a uniform speed ωr around the circle .

Therefore , acceleration of the particle = ω

2

r

= ω(ωr)

= ωv

Explanation:

Centripetal force is same on both as given.

So,
