The electric potential (voltage) at a specific location is equal to the potential energy per unit charge a charged object would have if it were at that location. if the zero point of the voltage is at infinity, the numerical value of the voltage is equal to the numerical value of work done to bring in a unit charge from infinity to that location. select values and grid in the menu, and drag one positive charge to the middle of the screen, right on top of two intersecting bold grid lines. using the voltage meter, you should find that 1 m away from the charge, the voltage is 9 v. what is the voltage 2 m away from the charge?

4.5 V

Explanation:

The electric potential produced around a single point charge is:

where

k is the Coulomb's constant

q is the charge

r is the distance from the charge

We see that the electric potential is inversely proportional to the distance, r, so we can write:

where

V1 = 9 V

r1 = 1 m

V2 = ?

r2 = 2 m

Solving the equation, we find the voltage 2 m away from the charge:

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )
