Question

forces equal to 3N,4N,5N and 6N act on a particle in directions respectively due north,south,east and west.FIND THE magnitude and direction of the resultant​

Answer 1

Just take the resultant in each vertical and horizontal directions and then take the resultant.
Look at the attached image.

Answer 2

Answer:

Step-by-step explanation:

hey !!! the resultant force will be Fr = 1N south + 1N west

                                                        Fr = (2)^1/2
