Question
An object of mass 2 kg is sliding with a constant velocity of 4 ms−1 on a frictionless horizontal table. The force required to keep the object moving with the same velocity is:
Answer: Option B
:
B
Ideally, a frictionless horizontal table has no resistance to motion.
Therefore, the object will continue to slide at 4 ms−1 without any application of force.
∴ The force required to keep the object moving = 0
