Question

To solve the problem below, you must write clear and convincing justification for accepting one of the possible answer choices as best or most appropriate and for rejecting each of the other choices as less appropriate. Your reasons for rejecting choices are just as important as your reasons for choosing the best answer.

If a positive point charge is released in an electric field, the charge moves in a straight line when:

a. The electric field lines are straight.

b. The voltage difference between any two points is zero.

c. The electric field lines are uniformly curved.

d. It is inside a conductor.

e. it is inside a uniformly charged conducting shell.

Explanation / Answer

ans. a
because the force on an positive electric charge is in the direction of the electric field (lines) , so if the electric field lines are straight the charge will move in straight line.

if the voltage difference is zero it will not move because positive charge always moves in the direction of decreasing potential or voltage.also if the voltage difference is zero ,electric field will be zero. so b is incorrect.

if the electric fields are curved it will move in cuve line along the field lines because force direction will change.

inside a conductor electric field is zero, so the chrage will not move because the force on the charge is 0.

again inside a conducting shell the electric field will be zero, so the charge will not move.
