Answer:

Force = 504.6 N

Explanation:

Weight, W = mg

Weight of object = 87 N

Effort length = 9.2 m

Resistance length = 3.4 m

The required length, h = Effort length - Resistance length

                                      = 9.2 - 3.4

                                      = 5.8 m

But,

F = mgh

  = W x h

F = 87 x 5.8

  = 504.6 N

The value of force required to lift the weight is 504.6 N.
