Question

If vectors OA,OB, and OC have the same magnitude R and the angle between OC and OA and OC and OB is 45, what is the sum of these vectors?​

Answer 1

$\sqrt{oa} {}^{2} + ob {}^{2}$

Answer 2

Explanation:

The sum will lies on the middle vector.

R cos 45 + R cos 45 + R

R/√2 + R/√2 + R

√2R(2+√2)
