Problem P. 4700. (January 2015)
P. 4700. A uniform metal disc of height \(\displaystyle h\) and of cross section \(\displaystyle A\) (\(\displaystyle h\ll \sqrt{A}\)) is moving at a great acceleration parallel to the symmetry axis of the disc (\(\displaystyle {a\gg g}\)). How many electrons appear at that side of the disc which is opposite of the direction of the acceleration?
