Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFExplanation:
- From Newton's first law of motion, we know that a moving object will continue to move unless an external force is applied.
- Here, for our case, an object of mass 5 kg is sliding with a constant velocity of 12 m/s on a frictionless horizontal table hence no external force is applied to the object.
- Therefore no force is required to keep the object moving with the same velocity.
- Hence 0 N is the correct option.
Mistake Points
- The surface on which the object is moving must be horizontal and frictionless, otherwise frictional and gravitational force will also come into play.
Important Points
- If we need to change the speed and direction of the object then we need to apply some external force.
