A physical quantity which has direction as well as magnitude is known as vector,
- Displacement has both magnitude and direction.
- The sum of three vectors, having unequal magnitude, can be equal to zero.
4.If P ⃗ + Q ⃗=0, P ⃗and Q ⃗ have the same magnitude.
- Vector R ⃗ and –R ⃗ have the same directions.
6.All basic quantities are scalar.
- A vector quantity has no direction.
- A weight vector and a displacement vector can be added.
- The magnitude of the resultant of the force 6 N east and a force of 8 N no
