Question

A body of mass 2 kg is moving on a smooth floor in straight line with a uniform velocity of 10 m/s. Resultant force acting on the body is (in N)

Answer 1

Answer : 20 N

Solution :
_________

Given that :

Mass = 2 kg

velocity = 10m/sec

Also given that with uniform velocity so time = 1 sec

From the second law of motion :

$F = \frac{P}{t} \\ \\ = > F = \frac{mv}{t} \\ \\ = > F = \frac{2 \times 10}{1} \\ \\ = > F = 20$

So, the force will be 20 N.

Answer 2

Answer:

answer is 0

Explanation:

answers is zero because no realative motion acting or friction on smooth floor is less
