Answer
Case A
From the figure,
- Magnitudes of applied forces are 3 N, 7 N and 2 N.
- All forces are acting in the same direction.
Then,
Resultant force = 3 + 7 + 2 = 12 N (Towards right)
Case B
From the figure,
- Magnitudes of applied forces are 7 N, 7 N and 3 N.
- Both forces with magnitude 7 N each, are acting in the same direction while 3 N force is acting in their opposite direction.
Then,
Resultant force = (7 + 7) - 3 = 14 - 3 = 11 N (Towards right)
Case C
From the figure,
- Magnitudes of both applied forces is 5 N.
- Both forces are acting in the opposite direction.
Then,
Resultant force = 5 - 5 = 0 N
