A 40 N block is supported by two ropes. ...

A 40 N block is supported by two ropes. One rope is horizontal and other makes an angle of `30^(@)` with the ceiling. The tension in the rope attached to the ceiling is approximately

A

80 N

B

40 N

C

`40sqrt(3)N`

D

`(40)/(sqrt(3))N`

Text Solution

Verified by Experts

The correct Answer is:
A
(a) `T sin 30^(@)=w=40N`

` therefore" " (T)/(2)=40" or " 80N`
