Question

to
If A = 3i + 4 j and B = 7î +24), the vector which has the same magnitude as B and parallel
A is
Ã
c) 20i +15)
b) 15i +10
d) 15i + 20) idi
a) 5i+20​

Answer 1

Answer:

The vector whose magnitude is of B and parallel to A is 25(3i+4j)/5=15i+20j

Answer 2

Answer:

d)15i+20j

Explanation:

|B|=$\sqrt{49+576}$

=25

(|B|.Ä)/|A|

25/5*(3i+4j)

=15i+20j
