Determine electric potential at a point due to a point charge (IMP) 6. Determine relation for capacitance of parallel plate capacitar 7 Discuss Charging and discharging of a capacitor in detail. NUMERICALS: 1. A capacitor has a capacitance of 2.5*10* F. In charging process, electrons are removed from one plate and placed on the other one. When a potential difference between the plates is 4sov. How many electrons have been transferred? 2. Two opposite point charges each of magnitude "q" are separated by a distance 2d. What the electric potential at a Point "p" mid-between them 3. A Panicle having a charge of 20 electrons on it falls through a potential difference of 100 volts. Calculate the energy acquired by it in electron volts (eV). (IMP) 4. The electronic Nash attachment for a camera contains a capacitor for storing the energy used to produce the flash.
