A block of mass 30 kg is suspended by three string as shown in fig, Find the tension in each string.

A

`T_(1)=25N`

B

`T_(2)=25N`

C

`T_(1)=25sqrt(3)N`

D

`T_(2)=25sqrt(3)N`

Text Solution

Verified by Experts

The correct Answer is:
A, D
`T_(2) cos 60^(@)=T_(1) cos 30^(@)`..(i)
and `T_(2) sin 60^(@) + T_(1) sin 30^(@) = 5g` …(ii)
From Eqs. (i) and (ii)
`T_(1)=25N and T_(2)=25sqrt(3)N`.
