How would you explain to a friend who had never taken a physics course (a) What is an electric field? (b) What are electric field lines? (c) How does the electric field lines of a positive charge differ from that of a negative charge? A proton and an electron are released from rest in the center of a capacitor. (a) Is the force ratio (Force on proton/Force on electron) greater than one, less than one or equal to one? Explain. (b) Is the acceleration ratio (acceleration of proton/acceleration of electron) greater than one, less than one or equal to one? Explain
