Question

Vector product of a vector =3icap _ 4jcap_ 5k cap and b vector =_2icap +jcap_3kcap

Answer 1

A = 3i-4j-5k

B = -2i+j-3k

Vector product of two vectors is their cross vector.

So,

A×B = (3i-4j-5k)×(-2i+j-3k)

=>3i(-2i+j-3k)-4j(-2i+j-3k)-5k(-2i+j-3k)

=>0+3k+9j -8k+0+12i+10j+5i+0

=>17i+19j-5k
