I'm having trouble understanding charges on Earthed plates I think.
I know the answer for this question is that the ball will be attracted to the high voltage plate and stay there but I do not know why is that.
A light metal ball is suspended between two metal plates. One plate is earthed and the other is connected to the positive terminal of a high voltage supply. The ball will: ?
The Attempt at a Solution
I've been thinking about it and I'm not sure why I'm wrong about this question. In my opinion, the earthed metal plate would be devoid of electrons (since they all escaped to the Earth?) so it would be positively charged. So wouldn't the ball be more attracted to the earthed plate rather than the voltage positive plate? I'm not really sure
