Question

If A = 2i +3and B=i- then componet of A perpendicular to vector B and in the same plane
is
(1-2)
(21)​

Answer 1

Answer:

Explanation:

Given:a→=2i^+j^+k^ b→=i^+2j^+k^∴ a→×b→=i^j^k^211121 =1-2 i^ -2-1 j^ +4-1k⏜ =-i^-j^+3k^⇒a→×b→=1+1+9 =11Unit vector perpendicular to the plane containing vectors a→ and b→=±a→×b→a→×b→Unit vector perpendicular to the plane containing vectors a→ and b→=±111-i^-j^+3k^ Q4

Answer 2

Answer:

If ,

given a = 2i + 3

then automatically ,

perpendicular a is the vactor of perpendicular of b
