Two particles of equal mass are connected to a rope AB of negligible mass, such that one is at end A and the other dividing the length of the rope in the ratio 1:2 from A.The rope is rotated about end B is a horizontal plane. Ratio of the tensions in the smaller part to the other is (ignore effect of gravity)

A

`4:3`

B

`1:4`

C

`1:2`

D

`1:3`

Text Solution

Verified by Experts

The correct Answer is:
A
`T_(2) = mw^(2) (3r)`

`T_(1) - T_(2) = mw^(2)r`
`rArr T_(1) = mw^(2)(4r)`
`T_(1) : T_(2) = 4:3`
