As you have seen, charged particles interact with each other in such a way that there are forces between them. The electric field is defined in terms of this force. If the idea of force is needed to define the electric field, you might wonder what the point of the electric field is. That is, why bother to define a new concept if the concept of force is sufficient to explain the interactions between charges? In the next group of activities, you will investigate the answers to this question. Open Physlet Lab_C4. The simulation shows a +4 C charge and a +1 C charge. The +1 C charge will be considered as the "test charge" that will be used to investigate the electric field established by the +4 C charge. When the simulation is first opened, the +4 C charge is at the point (0,0) and the test charge is at the point (1 m, 1 m). 15) Drag the test charge to the point (2 m, 2 m). How does the force on the test charge at this point compare to the force it experienced when it was at the point (1 m, 1 m)? I need each and every step with proper explanation
