Question
The picture below shows a particle (labeled B) which has a net electric charge of +1 unit. Several centimeters to the left is another particle (labeled A) which has a net charge of -2 units. Choose the pair of force vectors (the arrows) that correctly compare the electric force on A (caused by B) with the electric force on B (caused by A). In the figure below, positive charges q_2 and q_3 exert on charge q_1 a net electric force that points along the +x axis. If a positive charge Q is added at (b. 0), what now will happen to the force on q_1? (All charges are fixed at their locations.)Explanation / Answer
7.
b
the force applied by A on B is equal in magnitude to the force applied by B on A
the force applied by A on B is opposite to the force applied by B on A
8. b
with the addition of Q , there will be additional force on q1 in positive X-direction. hence the magntitude of net force will increase
