Two forces are acting on a particle at the origin. One force is acting in the first quadrant at 45o with 20 N and the other is acting in the second quadrant at 45o with respect to the negative x-axis also with 20 N. If the mass is 2.0 kg, the net force on this mass is Group of answer choices 10 N 15 N 40 N 28 N zero N
