Question

# Parallelogram law is used when _______

- Two tails of the vectors are connected
- Two heads of the vectors are connected
- Vectors are not connected
- None of the above

Hint:

### Two tails of the vectors are connected

## 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.
