Beads `A` and `B` each of mass `m` , are connected by a light inextensible cord. They are constrained (restricted) to move on a frictionless ring in a vertical plane as shown. The beads are released from rest at the position shown. The tension in the cord just after the release is.

A

`mgsqrt(2)`

B

`(mg)/(sqrt(2))`

C

`(mg)/(2)`

D

`(mg)/(4)`

Text Solution

Verified by Experts

The correct Answer is:
B

On block `B :`
`mg-T cos 45^(@)=ma …..(i)`
on block `A:`
`Tcos 45^(@)=ma ….(ii)`
by equation `(i)` and `(ii)`
`T=(mg)/(sqrt(2))`
