Question

Please someone Answer!!!!!                              

A red and a blue balloon are each rubbed against a woolen sweater. Doing this gives the balloons equal negative electric charges. If the balloons are tied to the same meter stick, which diagram represents the system with greatest amount of electrical potential energy?

Answer 1

It's B lol they are being forced apart but can't move because the are tied down

Answer 2

B

Step-by-step explanation:

The expression which represents electric potential energy is given by

`U_(E)(r)=k_(e){(qQ)/(r)}`

Where q and Q are the charges in the balloons

r = Distance between the charges or balloons

k = Coulomb's constant

It can be seen that the potential energy varies inversely with distance. This means that if the distance decreases the potential energy will increase.

In case B the distance between the balloons is the lowest so the electric potential energy will be maximum.
