A uniform rope of length of length `L` is pulled by a force `F` on a smooth surface. Find tension in the rope at a distance `x` from the end where force is applied.

Options

A. P
B. `P(1-(x)/(L))`
C. `((Px)/(L))`
D. `P(1+(x)/(L))`

Answer

B

Explanation

`F=marArra=(P)/(m)`

`T=m'a=(m)/(L)(L-x)(P)/(m)`
`=P(1-(x)/(L))`
