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.
