A rope of mass 0.1 kg is connected at the same height of two opposite walls. It is allowed to hang under its own weight. At the contact point between the rope and the wall, the rope makes an angle ` theta = 10^(@)` with respect to horizontal. The tension in the rope at its midpoint between the wall is

A

2.78 N

B

2.56 N

C

2.82 N

D

2 .71 N

Text Solution

Verified by Experts

The correct Answer is:
C
`2T sin theta = mg`
`rArr T = (mg)/(2 sin theta) = (0.1 xx 9.8)/(2 sin 10^(@))`
`rArr T = 2.82 N`
