Question
Select True or False for the following statements about electric field lines.
True False Where the E-field lines are dense the E-field must be weak.
True False E-field lines point inward toward negative charges.
True False E-field lines point outward from positive charges.
True False A positive point charge released from rest will initially accelerate along an E-field line.
True False E-field lines may cross.
True False E-field lines make circles around positive charges.
True False E-field lines do not begin or end in a charge-free region except at infinity.
Explanation / Answer
The electric field is strong where the electric field lines are dense. Hence the given is False
Electric field lines are directed from positive to negative, This means lines starts from positive charge and ends at negative charge, hence they are directed towards negative charge,. Hence the given is True.
Electric field lines are directed from positive to negative, This means lines starts from positive charge and ends at negative charge, hence they are directed outwards positive charge,. Hence the given is True.
Electric field lines are directed from positive to negative, So, the positive charge released in an electric field reppeld by positive charge and it will follow the path of electric field lines, Hence the given is True.
Electric field lines will not intersect or cross with each other, because at the point of intersect there are two directions for the electric field, which is not possible, hence the given is False.
Electric field lines are not closed lines, they starts from the surface of the charge and ends at the surface of the charge, Hence the given is False.
Electric field lines will exists only in the chraged region, So the given is False.
