MCQ
Following sets of three forces act on a body. Whose resultant cannot be zero
- A$10, 10, 10$
- B$10, 10, 20$
- C$10, 20, 23$
- ✓$10, 20, 40$
✓
Answer
Correct option: D.
$10, 20, 40$
d
(d) From the triangle law of vector addition the resultant must be zero if sum of two forces $\geq$ remaining force. If you check for all option only option $D$ not valid for it because $10+20=30<40$
