Determine the following. (a) the change in the electric potential energy (in J) of the object-field system 0.000676 x If an object is acted on by a conservative force, how is the change in potential energy related to the work done on the object by a conservative force? Did you forget about the minus sign? J (b) the electric potential difference (in V) through which the object moves 52 How is the electric potential difference related to the electric potential energy? Knowing the change in electric potential energy from part (a) and the charge, how can you determine the electric potential difference? Remember to convert the charge from C to C. V Need Help?

Its speed is reduced to 1.90 105 m/s at the point x = 2.00 cm. (a) Calculate the electric potential difference between the origin and that point. 98.3 The response you submitted has the wrong sign. Volts (b) Which point is at the higher potential? the point x = 2.00 cm the origin both have the same potential
