Question

# Parallelogram law is used when _______

## Two tails of the vectors are connectedTwo heads of the vectors are connectedVectors are not connectedNone of the above Hint:

## The correct answer is: Two tails of the vectors are connected

### Parallelogram law is used when two tails of the vectors are connected. Two vectors have the same initial point hence, they have the same initial point.

In parallelogram law of vector addition, it says that if we place two vectors so they have the same initial points(the tails are connected) and then complete the vectors into a parallelogram, then the sum of the vectors is directed diagonal that starts at the same point as the vectors.

### If the vectors are of the same magnitude and same direction, they are said to be

Two vectors are said to be equal if they have same magnitude and direction, regardless of the positions of their positions of their initial points.
