Solution

The correct option is A

Given: Distance moved by load = 5 m

In a single fixed pulley system, the distance moved by effort is equal to the distance moved by load.

Distance moved by effort = Distance moved by load = 5 m

VR $= \frac{D i s t a n c e m o v e d b y e f f o r t}{D i s t a n c e m o v e d b y l o a d} = \frac{5}{5} = 1$
