Question

The magnitudes 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

Answer: (E)

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