A positive charge is placed in an electric field. It starts at rest but is free to move. What does the test charge do? It stays at rest. It moves towards the nearest negative charge only (if there is one). It moves along electric field lines in the opposite direction the arrows point It feels a force pointing tangent to the field lines and moves according to the force. Three charges, -9, +q, and -2q are...

select True or False for the follwing statements about electric field lines. A positive point charge released from rest will initially accelerate along an E-field line. E-field lines make circles around positive charges. E-field lines point inward toward negative charges. E-field lines may cross. E-field lines point outward from positive charges. Where the E-field lines are dense the E-field must be weak. E-field lines do not begin or end in a charge-free region except at infinity.

A proton is released from rest in a uniform electric field. Which statement is correct? The proton will move in the opposite direction as the electric field to regions of lower electric potential. The proton will move in the same direction as the electric field to regions of lower electric potential. The proton will move in the opposite direction as the electric field to regions of higher electric potential. The proton will move in the same direction as the electric...

A constant electric field is in
the positive X direction as shown in the diagram below. Also shown
are two paths through which a charge can move from point A to point
C. In the first path, the charge moves directly from A to C. In the
second path path the charge moves parallel to the Y-axis to B and
then parallel to the X-axis to C.

Some unknown charge moves in a direction perpendicular to the direction of the electric field lines. We can conclude that: It moves from a high potential to a low potential, and its electric energy increases. It moves from a low potential to a high potential, and its electric energy increases. It moves from a high potential to a low potential, and its electric energy decreases. Both its electric potential and electric potential energy stay constant. It moves from a low...
