A charge of 0.10C accelerated through a potential difference of 1000V acquires kinetic energy
Correct answer: D. 100J
- A. 200J
- B. 10J
- C. 10eV
- D. 100J
Explanation
We know that Work(W) = Electric potential(V). charge(Q)According to work energy principle W= ΔK.EK.E=V.Q = 0.10 X 1000 =100 J

About Electrostatics
Electrostatics describes forces between charges through Coulomb's law, electric fields and field intensity, then uses electric potential to measure energy per unit charge. Capacitors store charge and electrical energy, with capacitance depending on geometry and dielectric material, not simply on the amount of charge present.
