Question

An object is attached to a spring scale, which reads 2 N. If the same object were attached to two identical spring scales placed sideby side, what would be the readings on each spring scale?

Answer 1

The readings of the scales will have to add 2N. This comes from the fact that each scale is supporting a part of the weight of the object. Now, if the center of gravity is midway between the two scales the readings will be the same on each spring scale; assuming this is the case the reading on each scale is 1N.
