Figure N-6

-Two 50-N weights pull on the scale as shown. The reading on the scale is
A)0 N.
B)25 N.
C)50 N.
D)100 N. This is clearer to understand if we think of the situation this way:
E)Since no acceleration is taking place, the forces cancel one another.
F)One of the weights "holds" the scale while the other weight stretches the spring.
G)The two hanging weights provide forces that constitute an action/reaction pair.
