This is an applet-based homework assignment that allows students to explore the electric field due to a point charge. The strength of the field can be measured at any coordinate in the x-y plane. The task is to calculate the magnitude of the charge, plot the strength of the field as a function of the radial distance from the charge, and compare this to Coulomb's Law.
This item is part of a larger collection of applet-based learning activities and homework assignments, designed to give student interactive support in understanding physics concepts.
