A10-lb weight is suspended from two accurate spring scales, each of which has negligible weight. what will be the weight readings on the scales?

the top scale will measure 0 lb and the lower scale will measure 10 lb.

both scales will measure 10 lb.

each scale will measure 5 lb.

the lower scale will measure 0 lb and the top scale will measure 10 lb.

The answer is: Both scales will measure a weight 10 lb

From the options, we can know that both spring scales are in series:

It's like there are just one scale composed by two scales since the statement states that both has negligible weight, so both scales will be reading the whole weight.

Calculations:

So, if tension is equal to weight, it means that both scales will be reading a weight of 10 lb.

Have a nice day!

the answer to this is proletariats.

hope this : )
