Question

The answer is negatively charged. Please explain to me why.

21. In Figure P30.21, a charged particle has been suddenly ac-
celerated downward, producing the electric field line pattern
shown. When the kinks in the field lines reach the metal rod
at the left, they produce a downward current in the rod. Is
the particle that has been accelerated positively or negatively
charged? .
