UPSC 2004: A car is running on a road at a uniform speed of 60 km/hr. The net resultant force on the car is
(a)Driving force in the direction of car’s motion
(b)Resistance force opposite to the direction of car’s motion
(c)An inclined force
(d)Equal to zero
Attempt This Question
Not attemptedCorrect Answer: (d) Equal to zero
A car moving at a uniform 60 km h⁻¹ has zero acceleration; under Newton’s first law, the vector sum of all forces must therefore be zero. Driving force and resistive forces cancel, giving a net resultant force of zero – option (d).
