Question

Under what condition the three vectors cannot have zero resultant?

Answer 1

Let the three vectors be x, y, z

Then,

Z should not be a number between (x+y) and ( x-y)

For example,

Let the three vectors be 4 , 6, 1

Then,

As 1 is not in between (6+4) and(6-4)

The resultant can never be ‘0’
