When taking a photo of a nearby flower, your camera lens should
be set
a) closer than one focal length from the photosensitive surface
b) farther than one focal length from the photosensitive surface
c) to one focal length from the photosensitive surface - ANSWER-
b) farther than one focal length from the photosensitive surface →
you want it beyond the focal point
Which of the following can be projected onto a viewing screen?
a) Real image
b) Virtual image
c) [both of these]
d) [neither of these] - ANSWER-a) Real image

Electric potential, measured in volts, is the ratio of electrical
potential energy to the amount of electric
a) current
b) resistance
c) charge
d) voltage
e) [none of these] - ANSWER-c) charge
EPE = PE/q
V = I/R
V = J/C
If 10 J of work is used in pushing a 1-C charge into an electric
field, its electric potential relative to its starting position is
a) less than 10 V
b) 10 v
,3|Page
c) more than 10 V
d) [none of these] - ANSWER-b) 10 v
10 J/ 1 C = 10 Volts
energy is not lost or gained so it is 10 V
An electron is pushed into an electric field where it acquires a 1-V
electric potential. If two electrons are pushed the same distance
into the same electric field, the electric potential of each electron
is
a) 0.25 V
b) 0.5 V
c) 1 V
d) 2 V. E) 4 V - ANSWER-c) 1 V
The net charge on a parallel-plate capacitor depends on
, 4|Page
a) the area of the capacitor plates
b) the distance between the capacitor plates
c) the medium between the capacitor plates
d) [all of these]
e) [none of these] - ANSWER-d) [all of these]
Q=C
∆V = Eo * A/d * ∆V
∆V = battery
What is the unit for electric charge? - ANSWER-Coulomb, C
The electrical force between charges is strongest when the
charges are
a) close together
