Reference no: EM138948

Q1. Two 18 cm diameter charged disks face each other, 25 cm apart. Both disks are charged to - 30 nC. What is the electric field strength at the midpoint between two disks?

Q2. A small object with a mass of 420 mg carries a charge of 35.0 nC and is suspended by a thread between the vertical plates of the parallel-plate capacitor. The plates are separated by 3.00 cm. If the thread makes an angle of 19.0° with the vertical, what is the potential difference between the plates?
