Question
Consider a negative charge q placed in a uniform electric field as shown in the
figure below. Find the change in the electric potential energy ∆Uelec for these cases:
(1) The charge moves up distance d.
(2) The charge moves down distance d.
(3) The charge moves sideways (90◦ to E~ ).
Expert Solution
Step 1
Electric force on a negative charge will be in opposite direction of electric field in space.
Change in electric potential energy of charge is equal to negative of work done by electric force on the charge.
