A 10-N falling object encounters 4 N of air resistance.The net force on the object is
A)0 N.
B)4 N.
C)6 N.
D)10 N.
E)none of these

Question

Quizplus · Accepted Answer

The net force on any object is equal to the difference between its weight and the net force of all the resistive forces acting on it. Given that the weight of the falling object is 10 N and air resistance is opposing it with a force of 4 N, the net force acting on the object is:

Net Force = Weight - Air Resistance
Net Force = 10 N - 4 N
Net Force = 6 N

Hence, the correct answer is C) 6 N.
