Question

23. a.b = O implies that a and b are:
O Perpendicular
O Parallel
O Non-parallel
O Oblique​

Answer 1

Answer:

perpendicular

Explanation:

a. b=|a|*|b|*cos(angle b/w a and b) ;

if a. b=0,then cos(angle b/w a and b) becomes zero.

we know cos(90)=0;

so a and b are perpendicular to each other.
