Chapter 17: The Electric Field 4N
Two charges that are separated by
one meter exert 1-N forces on each
other. If the magnitude of each
charge is doubled, the force on
each charge is A) 1 N. B) 2 N. C) 4
N. D) 8 N. E) [none of these]
Two charged particles attract each F
other with a force F. If the charges
of both particles are doubled, and
the distance between them is also
doubled, then the force of
attraction will be A) F. B) 2F. C) F/2.
D) F/4. E) [none of these]
, Lillian safely touches a 100,000-volt energy transfer
Van de Graaff generator. Although
the voltage is high, the relatively
small amount of charge means a
relatively small amount of A) energy
transfer. B) electric field. C)
polarization. D) conduction.
Chapter 18: Electric Potential 10 J
Assume that 10 J of work is required
to push a charge (initially at rest)
into an electric field. If the charge is
then released, it flies back to its
starting position with a kinetic
energy of A) zero. B) 5 J. C) 10 J. D)
more than 10 J. E) [need more
information]
Chapter 19: Electric Current 6 Joules
A coulomb of charge flowing in a
bulb filament powered by a 6-volt
battery is provided with A) 6 ohms.
B) 6 amperes. C) 6 joules. D) 6
watts. E) 6 newtons.
