##### What will happen if?
« on: 10/09/2016 14:53:56 »
Equipment

1 set of pan scales

2 iron balls of equal mass

A high intensity laser

method.

On each pan place an iron ball so the scales read 0 and are level.

Emit the high powered laser at one of the balls so the balls entropy gains hf .

Will the scales move?

In a second experiment the iron balls are hanging from pieces of string, an equal height and a small distance apart.

Like the above we emit a laser at one of the balls, will the balls move?

Yes. Look up "radiation pressure" in your elementary physics book.

I am aware of radiation pressure that sort of proves light has physicality, but I think you mean the movement is push in this scenario , where I was looking for the affect of the entropy of the balls on each other.

When metal gains hf and gains ''mass'' and charge , the metal expands, so to the first question, if metal ball (A) gains hf and metal ball (B) remains at equilibrium entropy, should the scales tilt  to one side?

Which way , if they tilt, will they tilt?

I put a diagram to the question in case some of you are unsure.
