Homework Help: Physics/Math

Posted by COFFEE on Sunday, February 18, 2007 at 12:51am.

Given two vectors, a and b, such that a + b = a - b, find the magnitude of b.

Consider the equation
a + b = a - b
to be n vector notation and both a and b have components. Subtract the a vector from both sides. You are left with
b = -b
That can only be true if b = 0. That would make its magnitude also zero.
