Question

force equal to3N ,4N ,5N and 6N act on a particle in direction respectively due north ,South ,east , west . find the agnitude and resultant .

Answer 1

here is your answer by UDIT

force are acting on the coordinate axes so we do not need to take components

so forces are
3j
-4j
5i
-6i

so net force is (3-4)j + (5-6)i

that is -1i-1j

and the angle made by force is arc(-1/-1) =π/4 with east towards south
