Question

A force of magnitude 31.37 lb directed toward the right is exerted on an object. What other force must be applied to the object so that the resultant force is zero?

magnitude
direction	---Select--- to the right to the left

Answer 1

Here,

let the second force is F2

Now, for the net force to be zero

F1 + F2 = Zero

31.37 + F2 = 0

F2 = - 31.37 lb

hence , the second force needed is 31.37 lb applied to the left
