Question

How to find the magnitude of the cross product of two vectors?

Answer 1

Let A vector be i cap + j cap + k cap
Ler B vector be pi cap + pj cap + pk cap

To find the magnitude of A cross B

First find A cross B
Suppose A cross B come out to be Ai cap + Bjcap +Ck cap

use whole root over Asquare + Bsquare + Csquare and this will be your magnitude


Remember dont use i j k cap in magnitude as they only shows the direction.
