Question

The magnitude of a set of $3$ vectors are given below. The set of vectors for which the resultant cannot be zero is

• A. $15,20,30$
• B. $20,20,30$
• C. $25,20,35$
• D. $10,10,20$
• E. $10,20,40$

Answer 1

The correct option is E $10,20,40$

According to the triangle law, the addition of first two vectors is greater than third vector but in option $\left(e\right)$ this condition is not satisfied, $10+20<40$.
