| A. | V= ( frac {1}{4 pi varepsilon_o} ( frac {q_1}{r_1} + frac {q_2}{r_2} + frac {q_3}{r_3} + . frac {q_n}{r_n}) ) |
| B. | V=1 4 <sub>o</sub> ( ( frac {q_1}{r_1} + frac {q_2}{r_2} + frac {q_3}{r_3} + . frac {q_n}{r_n}) ) |
| C. | V= ( frac {1}{8 pi varepsilon_o} ( frac {q_1}{r_1} + frac {q_2}{r_2} + frac {q_3}{r_3} + . frac {q_n}{r_n}) ) |
| D. | V= ( frac {1}{4 pi varepsilon_o} ( frac {q_1}{r_1} times frac {q_2}{r_2} times frac {q_3}{r_3} times . frac {q_n}{r_n}) ) |
| Answer» B. V=1 4 <sub>o</sub> ( ( frac {q_1}{r_1} + frac {q_2}{r_2} + frac {q_3}{r_3} + . frac {q_n}{r_n}) ) | |
