The change in potential energy = negative work done. by conservative force Work done by conservative force is independent to the path shape.
A uniform electric field of (250N/C) towards the negative (x) axis. Calculate the change in potential energy of the electron when it moves from the point (5cm, -2cm) to the point (-2cm, 4cm) Calculate the work done by the electric field on the electron when it moves from the point (5cm, -2cm) to the point (-2cm, 4cm).
A proton moves in a uniform electric field of (250 N/C), as shown in the adjacent figure. Calculate the change in potential energy of the proton in the following cases: 1- When it moves from position a to position b 2- When it moves from position c to position b 3- When it moves from position a to position c.
A proton is placed between two parallel conducting plates in a vacuum The difference in electric potential between the two plates is 450 V. The proton is released from rest close to the positive plate. What is the kinetic energy of the proton when it reaches the negative plate?.
A metal ball with a mass of 3 * 10 ^ - 6 kg and a charge of +5.00 mC has a kinetic energy of 6 * 10 ^ 8 J. It is traveling directly at an infinite conducting plane of charge with a charge distribution of +4.00 C/m². If it is currently 1.00 m away from the plane of charge, how close will it come to the plane before stopping?.
Two parallel plates are held at potentials of +200.0 V and -100.0 V. The plates are separated by 1.00 cm. a) Find the electric field between the plates. b) An electron is initially placed halfway between the plates. Find its kinetic energy when it hits the positive plate.
