A car is running on a road at a uniform speed of 60 km/hr. The net resultant force on the car is:

1. The question states that a car is running on a road at a uniform speed of 60 km/hr. 2. Uniform speed implies that the velocity of the car is constant (assuming direction is also constant, i.e., running straight). 3. According to Newton's First Law of Motion, an object continues in its state of rest or of uniform motion in a straight line unless acted upon by a net external force. 4. Since the car is moving at a uniform speed (zero acceleration), the net resultant force acting on the car must be equal to zero. 5. This means the driving force is exactly balanced by the total resistance force (friction, air resistance etc.).
