Question

5 Magnitude of vector product of two unit vectors making an angle of Goo with each other is​

Answer 1

Answer:

$\sqrt3 A$

Explanation:

Assume two vectors of equal magnitude represented by $\vec A$

Then by vector addition their sum will be $\sqrt\vec A^2 + \vec A^2 + 2\vec A\vec Acos60$

= $\sqrt {2\vec A^2+ \vec A^2} = \sqrt {3\vec A^2} = \sqrt 3 \vec A$

Takes time to write answer like this so mark as brainliest to show appreciation.
