WebStep 1: Unit vector along A For a vector parallel to A, we need to find a unit vector along A Unit vector: A^= ∣ A∣ A = (3) 2+(4) 23 i^+4 j^ = 53i^+ 54j^ Step 2: Required vector Now we need the vector parallel to A to have a magnitude of B ∣ B∣= (7) 2+(24) 2=25 ⇒ Required vector =25× A^=25(53i^+ 54j^) =15 i^+20 j^ Hence, Option (D) is correct. WebDec 8, 2016 · C = B =√49+576 =25 Also, A and C have same directions,so ∴A (cap) = C (cap) { A (cap) means unit vector of A} ⇒ (3i+4j)/ (√9+16) = (xi+yj)/ C ⇒ (3i+4j)/5 = (xi+yj)/25 ⇒xi+yj=15i+20j Hence, the new vector C=15i+20j Advertisement Still have questions?
