Let  begin mathsize 14px style B with rightwards arrow on top space cross times space A with rightwards arrow on top space end style =  begin mathsize 14px style C with rightwards arrow on top end style
begin mathsize 14px style C with rightwards arrow on top end style is perpendicular to vector begin mathsize 14px style A with rightwards arrow on top end style .
begin mathsize 14px style left parenthesis space B with rightwards arrow on top space cross times space A with rightwards arrow on top space right parenthesis times stack A space with rightwards arrow on top space equals space C with rightwards arrow on top space times space A with rightwards arrow on top space equals space 0 end style
scalr product  begin mathsize 14px style C with rightwards arrow on top times A with rightwards arrow on top end style is zero because begin mathsize 14px style C with rightwards arrow on top end style and begin mathsize 14px style A with rightwards arrow on top end style are perpendicular to each other
