A 10-newton force and a 15-newton force
are acting from a single point in opposite
directions. What additional force must be
added to produce equilibrium?
A 5 N acting in the same direction as the
10-N force
B 5 N acting in the same direction as the
15-N force
C 10 N acting in the same direction as the
10-N force
D 25 N acting in the same direction as the
15-N force
