A)Two charged particles exert an electrostatic force of 20N on each other. What will be the magnitude of the force if the distance
between them is increased to three times the original distance?

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .

hello there!

your answer is a “generator”

a generator does not create energy but instead it transforms it.

it’s basically a motor working in reverse.

probably not the "magnets"in the magnet, so to speak, are thought to be electrons orbiting in shells. vurrent loops two sides to the loop

graph question answered .. you think better when you are relaxed and happy
