Literacy 1. How does the electric
potential energy of a charged
object change if it moves:
a) perpendicular to the
direction of
b) in the same direction as;
c) in the opposite direction
to the Coulomb force acting
upon it?
2. When a positively charged
particle moves in a direction
parallel to the electric field,
how does its electric potential
energy and electric potential
change? Which force is doing
positive work?
3. You saw lightning many
times. Did you know that
clouds and Earth form
capacitor? Potential of earth
-50 000 Volts and potential
of sky is 200 000 Volts. Find
potential difference
