Question

If dot product of p and q is 0 then |p×q| is

Answer 1

Answer:

pq

Explanation:

If dot product of two vectors is 0 it means the vectors are perpendicular to each other (90 degrees)

So,

|p × q| = pqSin∅

= pqSin90

= pq

Answer 2

Answer:

p. q=0 , only if cosα=0

α=90

p cross b=pqsinα=pqsin90=pq
