The adjacent figure is the part of a horizontally stretched net. section AB is stretched with a force of 10 N . The tensions in the sections BC and BF are

A

10N,11N

B

10N,6N

C

10N,10N

D

cannot be calculated dir to insufficient data

Text Solution

Verified by Experts

The correct Answer is:
C
( c) As shown in figure

`T_(1) cos 30^(@) =T_(2) cos 30^(@)`
` therefore T_(1)=T_(2)=T` ( let)
Again, `T_(1) sin 30^(@) +T_(2) sin 30^(@) =10 " and " 2T sin 30^(@)=10`
`implies 2T.(1)/(2)=10 implies T=10 N`
Thus, the tension in section BC and BF are 10 N and 10 N respectively.
