Motion in a Plane - Result Question 51

54. Two particles of mass M and m are moving in a circle of radii R and r. If their time-periods are same, what will be the ratio of their linear velocities?

[2001]

(a) MR:mr

(b) M:m

(c) R:r

(d) 1:1

Show Answer

Solution:

  1. (c) Linear velocity v=rω

v1=ωr1,v2=ωr2

[ ω is same in both cases because time period is same]

v1v2=r1r2=Rr
