question on electric charge (1 Viewer)

[angmor]

since Eq=mg
(V/d)q = mg
Vq/d = mg

can you say that V is inversely proportional to q?

since Eq=mg
(V/d)q = mg
Vq/d = mg

can you say that V is inversely proportional to q?

For an electron you can't, because the charge on an electron is constant.

Now, would you be talking about this in terms of the Millian Oil Drop experiment or just any old charge experiment when the charge is prevented from falling due to gravity by an electric field of voltage V?

But, yes, you can say V is inversely proportional to q.

Obviously if q is a single electron (with a constant charge) then the size of V will be dependent on m and d (assuming g is also a constant - which is it ).
