The charge that flows is the rate of charge flow times the duration of the time interval.
The charge of one electron has magnitude e = 1.60 ! 10"19 C.
The rate of charge flow is 20, 000 C/s and t = 100 s = 1.00 ! 10"4 s.

Use constant acceleration eqns to calculate the upward acceleration a and then apply F = qE to calculate the electric field.
(Since the electric field is uniform, the force it exerts is constant and the e

When a positive charge moves in the
direction of the electric field,
A. the field does positive work on it
and the potential energy increases.
When a positive charge moves opposite
to the direction of the electric field,
