Question

) The magnitude of scalar product of two unit vectors perpendicular to each other is ​

Answer 1

This question involves the concept of the scalar product.

The magnitude of the scalar product will be "0".

SCALAR PRODUCT

The scalar product, also known as the dot product of the two vectors is given by the following formula:

$A.B = |A||B|Cos\theta$

where,

• A.B = Scalar product = ?
• |A| = Mangnitude of vector A = 1 unit
• |B| = Magnitude of Vector B = 1 unit
• θ = Angle between vectors = 90°

Therefore,

$A.B = (1)(1)Cos90^o = (1)(1)(0)$

A.B = 0
