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
. 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.
