Three particles describes circular path of radii r_(1), r_(2)and r_(3) with constant speed such that all the particles take same time to complete the revolution. If omega_(1), omega_(2), omega_(3) be the angular velocity v_(1), v_(2), v_(3) be linear velocities and a_(1), a_(2), a_(3), be linear acceleration then which of the follwing is not correct?

Answer»

`omega_(1): omega_(2): omega_(3)= 1:1:1`
`v_(1):v_(2):v_(3)= r_(1):r_(2):r_(3)`
`a_(1):a_(2):a_(3)= 1:1:1`
`a_(1):a_(2):a_(3)= r_(1):r_(2):r_(3)`
