When the al ball is charged, it will repel from the other al ball. the more charge on the al balls, the more repulsion. when both al balls have the same charge q, find an expression that lets you find the charge q from the measured separation distance r; i. e. a function q(r), which depends on the string length l, the al ball’s mass m, and the separation distance r between the al balls. make sure to have a schematic drawing as well.

answer: option c. i.e. electric current flowing “downhill” from the negative electrode to the positive electrode in a battery

explanation:

the water analogy to the circuits define the pipes (water flows) to the electric current. now, we know that the electric current flows from the positive terminal to the circuit (as shown in the diagram attached).

hence, option c is the correct answer.

we can see how the government has failed them.
