Question

If A vector =3^i +4^j and B vector =7^i +24^j , find a vector having the same magnitude as vector A and parallel to vector B.

Answer 1

I assume a vector c having same magnitude of vector A and direction along vector B
so the direction of vector B is
unit vector of B =
$\frac{7i + 24j}{ \sqrt{ {7 }^{2} + {24}^{2} } }$
then the vector c is
(3i+4j).(7i+24j)/square root of 7^2+24^2
I think , you may be understood

Answer 2

Answer:

Explanation:

If A 3 i 4 j
