An object is resting at the bottom of two strings which are inclined at an angle of `120^(@)` with each other. Each string can withstand a tension of 20 N. The maximum weight of the object that can be sustained without breaking the string is

A

10 N

B

20 N

C

`20sqrt(2)`

D

40 N

Text Solution

Verified by Experts

The correct Answer is:
B
(b) 2 T `cos 60 ^(@)`=w

or w=T or `w_("max")=T_("max")=20 N`
