There are two vectors `vecA=3hati+hatj` and `vecB=hatj+2hatk`. For these two vectors-
(a) Find the component of `vecA` along `vecB` in vector form.
(b) If `vecA & vecB` are the adjacent sides of a parallalogram then find the magnitude of its area.
(c) Find a unit vector which is perpendicular to both `vecA & vecB`.

Unit vector perpendicular to both `vecA&vecBhatn=(vecAxxvecB)/(|vecAxxvecB|)=(2hati-6hatj+3hatk)/(7)=(2)/(7)hati-(6)/(7)hatj+(3)/(7)hatk`
