Question

Four forces of magnitude 10n 5n 4n and 6n act on an object in the directions north west east and south respectively find the magnitude and direction of their resultant

Answer 1

net N-S ... 10 N - 6 N = 4 N north

net E-W ... 5 N - 4 N = 1 N west

magnitude ... m^2 = 4^2 + 1^2 ... m = √17

direction ... cos(Θ) = 1 / 4
... Θ is the degrees west of north

or ... (90 + Θ) on the unit circle

Answer 2

An object is placed by a force 10N to the east a force of 5N to the north west find the sum of these force given the magnitude and direction the three significant
