An electron is released from rest at the negative plate of a parallel plate capacitor and accelerates to the positive plate (see the drawing). The plates are separated by a distance of 1.2 cm, and the electric field within the capacitor has a magnitude of 2.7 x 106 V/m. What is the kinetic energy of the electron just as it reaches the positive plate?
Two parallel square metal plates (side length: 13 cm) are separated by a dielectric material with a dielectric constant 3.9 and a thickness of 2.4 mm. Find the energy stored on the capacitor
A small object with a mass of 380 mg carries a charge of 35.0 nC and is suspended by a thread between the vertical plates of a parallel-plate capacitor. The plates are separated by 5.00 cm. If the thread makes an angle of 12.0° with the vertical, ..
