Activity 5: Rope Mazes Form groups of 2-3 children, each with their own skipping rope and a few cones. Using their ropes and cones, each group makes a maze on the floor that involves a hopping and jumping challenge. Once all groups have finished, children circulate to other groups to try the different mazes.
The electric field strength is inversely related to the square of the distance. So by whatever factor d changes by, the E value is altered in the inverse direction by the square of that factor. The specifics are as follows: a) d increases by a factor of 2; divide the original E by 4.
Also the number of lines coming out of a charge or going in to the charge indicates the magnitude or strength of the electric field. For example each line might represent an electric field of 4 volts per cm, then for a 20 volt per cm field there will be 5 field lines. Since the electric field is proportional to the charge, then the number of field lines is also proportional to the magnitude of the charge.
