11. A negative charge (q = –2.0 Coulombs) is placed
above a floor that has a net positive charge. The floor
creates a uniform electric field that has a magnitude of
150 N/C.
(a) What is the magnitude and direction of the
electric force on the negative charge?
(b) If the charge is initially at a distance 1.0 m above the plane, what will the
change in electric potential energy (in Joules) be if it is then moved to a
distance 1.8 m above the plane (specify whether this change is
positive/negative/zero)?
12. If a proton moved from a location with 10 V potential to a location with 5.0 V
potential, would its potential energy increase or decrease? If an electron moved
from a location with 10 V potential to a location with 5.0 V potential, would its
potential energy increase or decrease? Explain.
I would appreciate any help. Thanks
