Calculate the magnitude and direction of the resultant force on an object that is acted on by a force of 4.0 N and a force of 10 N, that are
a) in the same direction
b) in opposite directions
c) at right angles to each other.
AS Physics Homework, thanks.

a) If the forces are in the same direction then they should be added algebraically
Resultant R = A + B
= 4 + 10 = 14 N
b) In opposite direction
Resultant R = 4 - 10 = -6 N
c) if at right angles then
Magnitude is R = sqrt (4^2 + 10^2)
= 10.77 N and
angle = tan(inverse) (4/10)
= 21.80 deg
I hope it helps.

a) F=4N+10N= 14N
b)F= 4N-10N= -6N or F=10N-4N=6N
c) F= Square root of 116. Diretion is given by constrution on paper with the rectangle whith 4 and 10 as sides. The diagonal is in the dierction of the force F.
The teacher is now going to admire you!
