Question

1. What is the voltage at the location of a 0.0006 C charge that has an electric potential energy of 0.7 J (both measured relative to the same reference point)? V

2.Two point charges are separated by 9 cm. The attractive force between them is 24 N. If the two charges attracting each other have equal magnitude, what is the magnitude of each charge?

3. A droplet of ink in an industrial ink-jet printer carries a charge of 4 10-13 C and is deflected onto paper by a force of 2.4 10-7 N. Find the strength of the electric field to produce this force.
N/C

4. The potential difference between a storm cloud and the ground is 100 million volts. If a charge of 7 C flashes in a bolt from cloud to Earth, what is the change of potential energy of the charge?
J

Explanation / Answer

Ans (1 ) It will be simply solved by the formula

potential energy W = voltage V x charge Q

so V=W/Q = 0.7/0.0006= 1166.66 v
