Question

at what condition the sum of two vectors will be zero?

Answer 1

If they point in the opposite direction and have equal magnitude!
Or
If both are Zero vectors! :D

Answer 2

consider vector A and vector B, they are of equal magnitude but opposite direction, then its sum will be obviously zero, and to prove this, we know that A and B have equal magnitude but opposite to each other so angle between them is 180, so [A+B=AB \sin (Angle)\] and sin 180 is zero,

Answer 3

thx guys

Answer 4

When the Vectors are Symmetric for example 3 and -3 .
means they are be ondirection .

Answer 5

@akashdhdeepDep equal magnitude ? This is not related to the zero Vectors .!!!
Just Symmetric Vectors .

Answer 6

Okay. :)
