That makes so much sense. So it isn't that R2 and R3 are zero, what happens is that R2 is short circuited and R3 is not connected to the circuit and therefore, they do not contribute any resistance to the total resistance of the circuit! Thank you!

That makes sense. So resistor 3 is not part of the circuit so it is not taken into consideration when calculation the total resistance. Is that correct? But I do not know which one is short circuited, how can I tell?

I am having trouble understanding short circuits and would appreciate some help with it. From what I understand, a short circuit occurs when we have a connection with a very low (zero) resistance is made between two points in a circuit. With R=0, the only resistance in our circuit would be...

I'm just going to add to what others have been saying. First you will want to draw a free body diagram for your sphere. Being able to visualize the situation will simplify the problem. Remember to include all the forces acting on the sphere: there's the force of gravity, the force of the...
