Question

find the force required to produce an acceleration of 2m/s² in an object of mass 10 kg​

Answer 1

Given, acceleration =2m/s  

2

.

Mass =10kg.

We know that,

Force=mass×acceleration

⇒Force=10×2=20N

If 30N force is applied on a body of 10kg mass,

Then acceleration =  

Mass

Force

​  

 

⇒Acceleration=  

10

30

​  

=3m/s  

2

.

Answer 2

a=2m/s²

m=10kg.

So the force requred to produce accleration of 2m/s² is equal to product of mass and acceleration.

i.e. F=m× a

So F=10×2

Therefore F=20N
