A charged particle moves along the x-axis in an electric field of 10 N/m that is also along the x-axis. This particle travels from 5 m away from the charge to 20 m away.
a. Determine the change in electric potential.
b. If this charge was determined to be 2.2 x 10^-6C then what is its change in electric potential energy?
c. Justly whether this charge would speed up or slow down in the field.
