Question

what is the dot product of two vectors of magnitude of 3 and 5 if angle between them is 60 degree

Answer 1

dot product = 15 cos60° = 15/2

Answer 2

Answer:

The dot product of two vectors of magnitude of 3 and 5 if angle between them is 60 degree is 15/2.

Explanation:

As per the given question:

Given That:

The two vectors of magnitude of 3 and 5 the angle between them is 60 degree.

To Find:

The dot product of two vectors of magnitude of 3 and 5 if angle between them is 60 degree.

Solution:

The total of the products of the matching components makes up the dot product, or inner product, of two vectors. It is equivalently equal to their product times the cosine of the angle between them. The square of a vector's magnitude is the dot product of the two.

The dot product of 15 cos60° is 15/2.
