Relation between i1 and i2​

Explanation:

I

1

and I

2

are two are at a distance a and b from COM.

Let I be the moment of inertia of a axis passing through it COM.

So,According to parallel axis theorem.

I

1

=I+Ma

2

I

2

=I+Mb

2

And,

I

1

−I

2

=M(a

2

−b

2

)

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.
