each other
B. A positive charge and a negative
charge will repel each other
C. Two positive charges attract each
other
D. A positive charge and a negative
charge attract each other
E. Electric charge is not conserved
Is it possible for the electric field E. Yes, regardless of the two charges
between two positive charges to
equal zero along the line joining the
two charges?
A. No, a zero electric field cannot
exist between the two charges
B. This cannot be determined
without knowing the magnitude of
the two charges
C. Yes, but only is the two charges
are equal in magnitude
D. This cannot be answered without
knowing the separation between
the two charges
E. Yes, regardless of the two
charges
, When a point charge of -q is A. The magnitude of the net electric field at the
placed on one corner of a square, center of the square is 0 N/C
an electric field strength 2.5 N/C is
observed at the center of the
square. Suppose three electrical
charge of -q are placed on the
remaining three corners of the
square. What is the magnitude of
the net electric field at the center
of the square?
A. The magnitude of the net electric
field at the center of the square is 0
N/C
B. The magnitude of the net electric
field at the center of the square is
7.5 N/C

field at the center of the square is
10 N/C
D. The magnitude of the net electric
field at the center of the square is 12
N/C
E. The magnitude of the net electric
field at the center of the square is

measured at a distance R from a
point charge Q. If the charge is
changed to 4Q and the electric
field is now measured at a distance
4R from the charge, the new
measured value of the field will be:
