If $\vec a,\vec b,\vec c$ are vectors such that $\vec a.\vec b=0$ and $\vec a+\vec b=\vec c$ then:
Answer & explanation
Correct answer: option 1
$|\vec a+\vec b|^2=|\vec c|^2$
$|\vec a|^2+|\vec b|^2=|\vec c|^2$
If $\vec a,\vec b,\vec c$ are vectors such that $\vec a.\vec b=0$ and $\vec a+\vec b=\vec c$ then:
Correct answer: option 1
$|\vec a+\vec b|^2=|\vec c|^2$
$|\vec a|^2+|\vec b|^2=|\vec c|^2$
