Q. A small object with a mass of 260 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 3.00 cm. If the thread makes an angle of 16.0° with the vertical, what is the potential difference between the plates?
