Question

two vectors a and b are inclined to each other at an angle of theta . which of the following is a unit vector perpendicular to both a and b
a - a cross b / a dotted with b
b- a cap x b cap/ sin theta
c - a vector x b cap/ ab sin theta
d - a cap x b vector/ ab sin theta

Answer 1

Answer:

Explanation:a×b=|a||b|sinΦ

Unit vector perpendicular to both a and b =a×b/|a||b|sinΦ

=|a|acap×|b|bcap/|a||b|sinΦ

=acap×bcap/sinΦ
