Two beads A and B of equal mass `m` are connected by a light inextensibe chord. They are constrined to move on a frictionless ring in vertical plane. The blocks are released from rest as shown in figure. The tension in the chord 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))`
