A small object with a mass of 270 μg carries a charge of 20.0 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 13.0° with the vertical, what is the potential difference between the plates?  V

Two isolated copper plates, each of area 0.4 m2, carry opposite charges of magnitude 7.08 × 10-10c oulombs. They are placed opposite each other in parallel alignment, with a spacing of 2 mm. What will be the potential difference between the plates when their spacing is increased to 4 cm?

For a point charge, the equipotential surfaces form concentric spheres with the charges at the center. 2 such equipotential surfaces have potentials 293.3V and 95.2V. if these 2 concentric surfaces are separated by a distance of 2.2m, what is the charge of the point particle?
