2 WEEK 1. ELECTRIC CHARGE AND DRAWING FIELD LINES 1.3 Definition of Electric Field 1. The gravitational field was defined in terms of the force on a test mass. For the electric field, should we specify that the test charge should be positive or negative? Does it matter which we choose? What would be the result if we made the other choice. 2. What does the direction of the field lines indicate? 3. What aspect of the drawing indicates the...

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.

(c) How are the Electric Field lines related to the equipotential lines? How do they cross each other? What does Eq. 11.2 indicate? Use a sketch to illustrate the relation of the Electric Field lines to the equipotential lines. (d) The Electric Field gives the direction in which a positive test charge would move from a given point in space. Explain why different lines of force can never cross each other.

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...
