Question

The example of dot product is ______.

Options

• angular momentum

• moment of force

• linear velocity in terms of angular velocity

• magnetic flux linked with the surface of magnetic induction

Answer 1

The example of dot product is magnetic flux linked with the surface of magnetic induction.

Explanation:

Magnetic flux is defined as ϕ = \[\vec B\] . \[\vec A\] = B A cos⁡ θ, which is the dot product of magnetic induction \[\vec B\] and area vector \[\vec A\], yielding a scalar, a classic example of the dot product.
