Which of the following is true regarding the electric field? O The electric field is produced due to the existence of the electrostatic force between two charges. The electric field needs to be setup first for the two charges to experience electrostatic force. Just like the electrostatic force, the electric field can exist even if there is only one charge in the system. O The electric field only exists when there are more than one charges in the system.

One end of a light spring with force constant k = 125 N/m is attached to a wall, and the other end to a metal block with charge qA = 2.00 C on a horizontal, frictionless table (Fig. P23.34). A second block with charge qB = 3.60 C is brought close to the first block. The spring stretches as the blocks attract each other so that at equilibrium, the blocks are separated by a distance d = 12.0 cm. What is the displacement x of the spring? Figure P23.34
