Find the resultant of the vectors shown in figure. |
Answer» Solution : `VEC(R) = vec(OA) + vec(AB) + vec(BC)` `vec(R) = (5 cos 37 hat(i) + 5 sin 37 hat(j)) + 3hat(i) + 4hat(j)` `vec(R) + 4hat(i) + 3hat(j) + 3hat(i) + 4hat(j)` `vec(R) = 7i + 7j, therefore R = 7sqrt(2) cm` and `alpha = 45^(@)` with HORIZONTAL |
