In an electric field, the lines on the left have twice the separation as those on the right. (a) If the magnitude of the field at A (particle in the field with lesser separated lines) is 58 N/C, what is the magnitude of the force on a proton at A? (b) What is the magnitude of ...

A particle has a charge of +1.5 C and moves from point A to point B, a distance of 0.18 m. The particle experiences a constant electric force, and its motion is along the line of action of the force. The difference between the particle's electric potential energy at A and B ...

1. Suppose that the strength of the electric field about an isolated point charge has a certain value at a distance of 1 m. How will the electric field strength compare at a distance of 2 m from the point charge? I know it's At twice the distance the field strength will be 1/4...
