Question

if vector a + vector B is equal to vector C then magnitude of vector C is equal to..​

Answer 1

Explanation:

We have,,

$\sf{\overline{A}+\overline{B}=\overline{C}}$

Therefore, magnitude of vector C is given by,

$\sf{|\overline{C}|=|\overline{A}+\overline{B}|}$

$\implies{\boxed{\sf{|\overline{C}|=\sqrt{A^{2}+B^{2}+2AB\cos(\Theta)}}}}$
