Electrons are emitted by a hot filament and are accelerated by an electric field as shown in figure (32-Q1). The two stops at the left ensure that the electron beam has a uniform cross-section.
(a) The speed of the electron is more at \( B \) than at \( A \).
(b) The electric current is from left to right.
(c) The magnitude of the current is larger at \( B \) than at \( A \).
(d) The current density is more at \( B \) than at \( A \).
