A body of weight 2 kg is suspended as shown in the figure. The tension `T_(1)` in the horizontal string (in kg wt ) is

Options

A. `2//sqrt(3)`
B. `sqrt(3)//2`
C. `2sqrt(3)`
D. 2

Answer

C

Explanation

`T cos 60^(@) = 20 `
`rArr T = 40 N `
`T sin 60^(@) = T_(1)`
`rArr T_(1) = 40 xx (sqrt(3))/(2) = 20sqrt(3)`
` rArr T_(1) = 2 sqrt(3)` kg wt
