Question

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

1 point

(a) 5 i +20 j

(b) 15 i + 10 j

(c) 20 i +15 j

(d) 15 i +20 j

​

Answer 1

Answer:

Magnitude of vector B = 25 units

|vec(A)| = 5 units

Vector parallel to A = 25 ( 3i + 4j ) / |vec(A)|

Vector parallel to A = 15 i + 20 j
