If A and B are nonzero vectors and A middot B 0 then A B i

If A and B are non-zero vectors and A middot B = 0, then A = B is Always true Sometimes true Always false

Solution

let us say A= ai +bj and B= xi + yj

then A.B =0

A.B = |A|.|B| cos(theta)

ax+by=0

ax=-by

if A=B then we get

a^2 = -b^2

this condtion never be true

so C). Always false
