Question

A 55.0 nC charge is fixed at the origin. Point A is 40.0 cm away from the origin and point B is 60.0 cm away from the origin a. If a point charge q is moved from A to B, while the -55.0-nc charge stays fixed at the origin, through what potential difference does it move? Volts b. If q -2.00 nc, what is the change in potential energy as it moves from A to B? Joules c. How much work does the electric field do as q is moved from A to B? Joules 60 cm 40 cm 55.0 nC

  • A +3.0 nC charge Q is initially at rest a distance of 10 cm(r₁) from a +5.0 nC charge

    A +3.0 nC charge Q is initially at rest a distance of 10 cm(r₁) from a +5.0 nC charge q fixed at the origin. Naturally, the Coulomb force accelerates Q away from q, eventually reaching 15 cm(r₂).The charge Q is repelled by q, thus having work done on it and losing potential energy. What is the work done by the electric field between r₁ and r₂? What is the change in the potential energy of the two-charge system from r₁...
