Question

A vector=icap+2jcap+2kcap,B vector=3icap+6jcap+2kcap,then the vector in the direction of A vector and having the same magnitude as modulous of B vector,is​

Answer 1

Answer:

Answer: $\frac{7}{3}$( i + 2j+2k)

Explanation:

Unit vector of  A  = (i + 2j +2k )/3 ; vector of B = ( 3i + 6j + 2k)

Mag of B = $\sqrt{9+36+4}$  = 7 ;

Vector of B in the direction of A = 7 x unit vector of A

= 7/3 ( i +2j +2k)
