A positive charge (g = +6.0 UC) starts from point A in a constant electric field and accelerates to point B. The work done by the electric force is WAB = +4.9 x 103 ). Determine the potential difference V3 - VA between the two points. Be sure to include the proper algebraic sign. Ε А B Ε V8 - VA = Number Units
How far from a - 3.6 μC point charge must a +6.0 μC point charge be placed for the electric potential energy of the pair of charges to be -0.5 J? (As usual, take the electric potential enregy to be zero when the charges have infinite separation.)
The drawing shows a point charge q = +1.6 JC and two locations A and B. What is the electric potential difference V8 -VA between these two locations? Be sure to include the proper algebraic sign. B 1.0 m A 2.0 m 4 V8 - VA = Number Units
Equipotential surfaces A positive point charge is surrounded by an equipotential surface A, which has a radius of rA. A positive test charge moves from surface A to another equipotential surface B, which has a radius rB. In the process, the electric force does negative work (a) Does the electric force acting on the test charge have the same or opposite direction as the displacement of the test charge? O The electric force has the same direction as the displacement...
