A mass of 10 kg is suspended from a spring so that it makes angle of `60^(@)` with the veritical . The new reading of the balance is

A

`10sqrt(3)` kg wt

B

`20sqrt(3)kg wt`

C

`20kg wt`

D

10 kg wt

Text Solution

Verified by Experts

The correct Answer is:
C

By Lami's theorem,
`(T)/(sin90^(@))=(10kgwt)/(sin150^(@))rArrT=(10)/(sin30^(@))=20`wt.
