the point charge Q = 5 nC creates an electric field around it, while the test charge q⁰ = 1nC is located at a distance r = 20cm from the center of the field 1.a) What is the work of the electric forces when the test charge shifts over the sphere with radius 20cm? b) how much is the work of electric forces when the test load is moved from a distance of 20cm to a distance of 10cm in relation to the center of the field?
