Question

.
14. An object of mass 2kg is sliding with a constant velocity of 4 m/s on a frictionless horizontal table.The force required to keep the object moving with the same velocity is-
a) 32 Newton
b) 0 Newton
C) 2 Newton
d) 8 Newton​

Answer 1

Answer:

$\huge{\mathcal{\red{A}\pink{N}\green{S}\blue{W}\purple{E}\orange{R}}}$

Given:-

• Mass of the given object=2kg
• Velocity=4m/s

To find:-

• The force required to keep the object moving with the same velocity?

Now:-

As we know from Newton's First Law of Motion an object will be in motion if there will no external or unbalanced force. Here the surface is frictionless and the object is travelling horizontally. So, there will be no force anting on it, which means that whole force will be 0.

Hence, zero force is required to keep the object moving with constant velocity, correct answer is B.

Your answer:- 0 Newton (option b)
