Two charged objects are separated by a distance d. The first charge is larger in magnitude than the second charge.
The first charge exerts a larger force on the second charge.
The second charge exerts a larger force on the first charge.
The charges exert forces on each other equal in magnitude and opposite in direction.
The charges exert forces on each other equal in magnitude and pointing in the same direction.
Two charged objects attract each other with a certain force. If the charges on both objects are doubled with no change in separation, the force between them
quadruples.
doubles.
halves.
increases, but we can't say how much without knowing the distance between them.
At twice the distance from a point charge, the strength of the electric field
is four times its original value.
is twice its original value.
is one-half its original value.
is one-fourth its original value.
Is it possible to have a zero electric field value between a negative and positive charge along the line joining the two charges?
Yes, if the two charges are equal in magnitude.
Yes, regardless of the magnitude of the two charges.
No, a zero electric field cannot exist between the two charges.
cannot be determined without knowing the separation between the two charges
Can electric field lines intersect in free space?
Yes, but only at the midpoint between two equal like charges.
Yes, but only at the midpoint between a positive and a negative charge.
Yes, but only at the centroid of an equilateral triangle with like charges at each corner.
No.
Two particles A and B have identical charge Q. For a net force of zero to be exerted on a third charged particle it must be placed:
midway between A and B
on the perpendicular bisector of the line joining A and B but away from the line
on the line joining A and B, not between the particles
on the line joining A and B, closer to one of them than the other
An electric field is most directly related to:
the momentum of a test charge
the kinetic energy of a test charge
the potential energy of a test charge
the force acting on a test charge
Choose the correct statement concerning electric field lines:
field lines may cross
field lines are close together where the field is large
field lines point away from a negatively charged particle
a charged point particle released from rest moves along a field line
