System shown in figure is in equilibrium...

System shown in figure is in equilibrium, find the magnitude of net change in the string tension between two masses just after, when one of the springs in cut, Mass of both the blocks is same and equal to m spring constant of both springs is k.
.

A

`(mg)/(2)`

B

`(mg)/(4)`

C

`(3mg)/(4)`

D

`(3mg)/(2)`

Text Solution

Verified by Experts

The correct Answer is:
A
Before cutting the spring

`T_(2)=mg`
After cutting the spring

`2mg-mg=2ma` ltbr. `a=g//2`
`T_(3)=mg//2`
`T_(2)-T_(3)=mg-(mg)/(2)=(mg)/(2)`
