Question
two cars of masses m &M are moving in circles of radii r & R their speeds are such that they make complete circle in same time t. ratio of centripetal acceleration
1) m:M
2)R:r
3)1:1
4) MR:mr
aieee 2012 is the ans is (4)
Joshi sir comment
since both make complete circle in same time t so angular velocities of the two will be same
now use F = mrω2
