The quantities having only magnitude and no direction are called

• Vector

• Scalar

• Tensor

• All the above

The vectors along the same line are called

• Equal Vectors

• Unit Vectors

• Collinear Vectors

• None of the above

Vectors lying on the same plane are called

• Unit Vectors

• Co-initial Vectors

• Zero Vector

A vector with zero magnitude is called

• Zero Vector

• Null Vector

• Both 1 & 2

• None of these

This is a vector, whose magnitude is unity. It is commonly used to represent the direction of a vector
