A rope of length 10m and linear density 0.5kg/m is lying length wise on a smooth horizontal floor. It is pulled by a force of 25 N. The tension in the rope at a point 6m away from the point of application is

A

20 N

B

15 N

C

10 N

D

5 N

Text Solution

Verified by Experts

The correct Answer is:
C
`"Force on unit length" =(F)/(L),`
`"Force on l units of length "=((F)/(L))l`
`"Tension at "(L-l)" length "=(F)/(L)(L-l)`
