A 2.30-kg mass is suspended from the ceiling and a 1.70-kg mass is suspended from the 2.30-kg mass, as shown. The tensions in the strings are labeled 
and 
.
?
?
Use this exhibit to answer the following question(s).
Refer to . A hand exerts an upward force of 6.70 N on the 1.70-kg mass. The magnitudes of the tensions are
A.
= 15.8 N; 
= 10.0 N.B.
= 15.8 N; = 16.7 N.C.
= 22.5 N; = 10.0 N.D.
= 22.5 N; = 16.7 N.E.
= 32.5 N; = 10.0 N.The magnetic force between parallel wires is used by the National Bureau of Standards to define the
