Question

four forces 10N,5N,4N and 6N
are on north , east, west and south direction. find their magnitude and direction.

Answer 1

forces in opposite directions will cancel , leaving net N-S and E-W forces

add the two vectors to find the resultant ... (N-S)^2 + (E-W)^2 = r^2

draw the vector diagram and use trig to find the direction angle

Answer 2

F = 10i + 5 + (-4) + (-6i) = 1 + 4i = 4.12N.[76o].
