,Two charges that C) 4 N
are separated by
one meter exert Explanation — Via Fe=k|q1||q2|/r^2, if
1-N forces on q1->2q1 and q2->2q2, then clearly a
each other. If the factor of 4 appears
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 A) F
particles attract
each other with Explanation — Via Fe=k|q1||q2|/r^2, if
a force . If the q1->2q1 and q2->2q2, and (2r)^2=4r^2,
charges of both then a factor of 4 cancels
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]
The electrical A) close together
force between
charges is
strongest when
the charges are
A) close
together. B) far
apart. C) [either
of these] D)
[need more
information]
, The electrical C) [both of these]
force between
electric charges
depends only on
their A)
magnitude
(strength of
charge). B)
separation
distance. C)
[both of these]
D) [neither of
these]

force on a 2-C
charge is 60 N.
The electric field
where the
charge is
located is A) 20
N/C. B) 30 N/C.
C) 60 N/C. D)
