1a 1386 nc charge is located at 01055 cm and a -38 nc, Ask an Expert

Academics

(1)A +13.86 nC charge is located at (0,10.55) cm and a -3.8 nC charge is located (4.43, 0) cm.Where would a -13.6 nC charge need to be located in order that the electric field at the origin be zero?

(2)Moving a charge from point A, where the potential is 398.3489 V, to point B, where the potential is 174.4013 V, takes 0.0005 J of work. What is the value of the charge?

(3)Two drops of mercury each has a charge on 0.0000000023 nC and a voltage of 243.81 V. If the two drops are merged into one drop, what is the voltage on this drop?
