Question

if |vec a + vec b| = |vec a - vec b| & a b are non zero vectors, then..?​

Answer 1

Answer:

a_b also 0 l think not sure

Answer 2

$|a + b | = |a - b|$

then we have that ,

=

$|a - b| = |a + b| = \sqrt{ { {a}^{2} + {b}^{2} } }$

and then both vectors are perpendicular to each other .

if you want i could give you explanation??

Hope it helps you
