Acharge of 6.7 × 10^-15 coulombs is located at a point where its potential energy is 5.6 × 10^-12 joules. what is the electric potential at that point?

a. 2.3 × 10^2 volts
b. 4.7 × 10^2 volts
c. 8.4 × 10^2 volts
d. 9.2 × 10^2 volts

C. 8.4 × 10^2 volts

Explanation:

The potential energy of a charge is given by:

where

q is the magnitude of the charge

V is the electric potential

In this problem, we have

is the charge

is the potential energy

Re-arranging the formula and using these numbers, we can find the electric potential:

answer: cesare beccaria developed the classical school of criminology with from philosopher jeremy bentham

explanation:

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
