How does the charge look like? Is it matter or energy?

Two small balls each having equal positive charge Q are suspended by two insulating strings at equal length L metre, from a hook fixed to a stand. The whole setup is taken in a satellite into space where there is no gravity. Find the angle between the two strings and tension in each of them.

why short occurs in this given electric circuit between AYFXB (why short offers zero resistance )?WHAT IS MEANING OF SHORT CIRCUIT?

I HAD UNDERSTOOD HOW TO FIND "R" (EQUIVALENT)TOTAL BY YOUR ANSWER BUT I AM HAVING TROUBLE IN UNDERSTANDING THAT HOW TO DISTRIBUTE "+"AND "-" SIGNS IN RESISTORS CORRECTLY IN AN ELECTRIC CIRCUIT.CAN YOU EXPLAIN HOW YOU HAD DISTRIBUTED "+"AND "-" SIGNS IN RESISTORS IN THIS QUESTION TO IDENTIFY PARALLEL AND SERIES COMBINATIONS OF RESISTORS?

But how to differentiate between series combination and parallel combination of resistors in a mixed combination of resistors(by distributing different value of current but how? ) ?

BUT IN CASE OF (WHEN CURRENT DOES NOT FLOW)POTENTIAL DIFFERENCE IS ZERO FOR A CHARGE SO WORK DONE SHOULD BE ZERO ,,,AND FOR WORK DONE TO '0' FORCE (F)*DISPLACEMENT(d)*COS THETA SHOULD BE Fdcos90(so force is acting perpendicularlyto displacement)?If AM I RIGHT THEN HOW THIS MOTION IS EXECUTED?

I DID NOT UNDERSTOOD THAT ""In actuality, it is the flow of electrons (from the negative terminal of a battery to the positive terminal ) which causes the electric current to be conducted in a circuit. Whereas the direction electric energy is (theoretically) said to be from the positive terminal of the battery towards the negative terminal of the body(SO IT MEANS THAT ELECTRONS FLOW FROM LOWER CONCENTRATION TO HIGHER CONCENTRATION,AND POSITIVE CHARGES FLOW OPPOSITELY (...IF YES?) BUT CONCENTRATION OF ELECTRONS WOULD BE LOWER IN "+"TERMINAL NOT "-"TERMINAL AS CONCENTRATION OF + CHARGES ARE HIGHER IN + TERMINAL ).HOW THIS IS HAPPEN SIMULTANEOUSLY?(WHAT IS THE DIRECTION IN WHICH CURRENT FLOWS?) ..AND IS POSITIVE CHARGES ARE POSITIVELY CHARGED ATOMS OR PROTONS

Two charges equal in magnitude and opposite in polarity are placed at a certain distance apart and force acting between them is F.if 75% charge of one is transferred to another, then the force between charges becomes?
