The above diagram shows a charged particle starting from position a, moving through two separate uniform electric fields in a uniform magnetic field, and eventually arriving at e. The direction of the magnetic field is upward, vertical to the plane. The path that the charged particle moves along is a \(\to\) b \(\to\) c \(\to\) d \(\to\) e. Which of the following explanations is correct?
a) The charged particle is positively charged.
b) The speed of the charged particle from position b to position c is constant.
c) The speed of the charged particle at position d is larger than that at position b.
