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.
As will be explained in the next episode, the unit for electric field strength can also be expressed as volts per metre, V m -1. Now, for the non-uniform field due to a point (or spherical) charge, we can use Coulombâs law to find an expression for the field strength.
