Question

the angle between vectors a and b is 60 degree the ratio A.B is divided by |AXB|??

Answer 1

Answer:

Explanation:

A.B =AB|cos60°

A×B=|AB|sin60°

Divide

Ratio we will get

1/2under root 3/2

Therefore

Ratio is 1/under root 3

Answer 2

Concept

A quantity that has both direction and magnitude, especially as a determination of the position of one point in space with respect to another.

Given

The angle between vectors a and b is 60 degree

Find

The ratio A.B

Solution

The steps are as follow:

a.b=|a||b|cos60°=|a||b|/2

a×b=|a||b|sin60°=√3|a||b|/2(direction

Now ratio is just 1:√3

So the ratio will be 1:√3
