Solution Verified by Toppr

Correct option is B)

As the surface is frictionless.

From newton's 1st law of motion, since there is no external force acting on the object, it will remain in its original state of motion i.e. uniform velocity.

Therefore, zero force is required to keep the object moving with constant velocity.

Hence, correct answer is B.

Question An object of mass 2 Kg

is sliding with a constant velocity of

4 ms

on a frictionless horizontal table. The force required to keep the object moving with the same velocity is

A 32 N B 0 N C 2 N D 8 N Open in App Solution

The correct option is **B**

0 N

**Step 1: Given data**

Mass, m = 2 kg Velocity, v = 4 ms-1

As the object is moving with a constant velocity i.e.,

4 ms-1

so the acceleration of the object is zero. i.e.,

a = 0

**Step 2: Finding the force required to keep the object moving with the constant velocity**

We know that Force=m×a

By substituting the given values in the expression, we get

Force=2×0 =0 N

Hence, option B is correct.
