Question1
A small object with a mass of 420 mg carries a charge of 40.0 nC and is pending by a thread between the vertical plates of a parallel-plate capacitor. The plates are unconnected by 4.00 cm. If thread makes an angle of 13.0° with the vertical, what is potential difference between those plates?
Question2
