# Question: Four identical spring scales A B C and D are

Four identical spring scales, A, B, C, and D are used to hang a 220.0-N sack of potatoes.

(a) Assume the scales have negligible weights and all four scales show the same reading. What is the reading of each scale?

(b) Suppose that each scale has a weight of 5.0 N. If scales B and D show the same reading, what is the reading of each scale?
