How does the electric potential energy between two charged particles change if one particle is reduced by a factor of 3? a. increased by a factor of 3 b. it is decreased by a factor of 9 c. it is reduced by a factor of 3 d. it is increased by a factor of 9

The electric potential energy is directly proportional to product of charges, hence when the particle charge is reduced by a factor of 3, the electric potential energy will also be reduced by a factor of 3.

Option C

Explanation:

Electric potential energy is the potential energy which is conservative to the respective coulomb forces between the two particle charges which are at a specified separation from each other.

Electric potential energy =

Where the k is the electrostatic constant,

q1 is the first charge.

q2 is the second charge.

r is the distance between q1 and q2.

dopamine..

"it was found that some people who were taking the drug l-dopa to raise their levels of dopamine were developing schizophrenic-like symptoms supporting research a strength of the dopamine hypothesis is that there are many studies which have shown support for the neurochemical explanation."

the answer is mosques. they are an important part of islamic culture.
