The weight needed to balance a lever varies inversely with the distance from the fulcrum to the weight. a 120-lb weight is placed on a lever, 5 ft from the fulcrum. what amount of weight should be placed 8 foot from the fulcrum to be balanced. a). 120 b). 75 c). 8 d). 125 i think, not 100% sure, like 90% sure, it's b. 75.

Let w represents the weight and d represents the distance.

It is given that

The weight needed to balance a lever varies inversely with the distance from the fulcrum to the weight. A 120-lb weight is placed on a lever, 5 ft from the fulcrum.

Substituting the values of w and d, we will get

Using the value of k which is 600, with the above equation and the given value of d which is 8, we will get

Therefore the correct option is B .
