MCQ
Does not vary from point to point in space Which pair of the following forces will never give resultant force of $2N?$
- A$1N$ and $3N$
- B$2N$ and $2N$
- C$1N$ and $1N$
- ✓$1N$ and $4N$
✓
Answer
Correct option: D.
$1N$ and $4N$
$1N$ and $4N$ will never give $2N$
mind it, if the side lengths of a triangle is $a, b, c$
$a + b > = c$
$b + c > = a$
$c + a > = b$
mind it, if the side lengths of a triangle is $a, b, c$
$a + b > = c$
$b + c > = a$
$c + a > = b$
