Please answer
5. An object of mass 2kg is sliding with a constant velocity of 4m/s on a frictionless horizontal table. The force required to keep the object with the same velocity is
a) 2 N
b) 8 N
c) 0 N
d) 0.5 N
Dear Student,
Answer to your question is given below:
Given, velocity = 4 m/s
mass = 2 kg
Now, we know that, F = ma
For v = constant, the acceleration, a = 0 m/s2
Hence, F = m x 0 = 0 N
Therefore option (c) is the correct choice.
Regards,
