you know I am from Egypt :smile: and i need ecludis to explain there are no ecludis nowadays

do you mean that the final voltage will be 500-316=184 and current will be 0.92 amp or i have to do something else thanks for your help dr i really appreciate it but my friend told me that the resulting voltage will be opposite in direction to that of battery can you explain how the capacitor...

do i have to say every time i post something that these questions are just out of book and i need quick answers my book doesn't contain a lot of info about the capacitor your posts arent helpful i am in vacation i just solve these questions to apply for a university test which will contain...

when the rod is put near to sphere A a positive charge accumulated on it and a negative charge on sphere B but I am really confused i think that both spheres can be positive so if you have an answer pls help and explain it :smile:

That's why i wrote the post Pgardn i don't know even the law... thanks for your help in advance

ask genill i don't know i didnt get anything from all you wrote i wanted the laws or formulas to get potential difference in volts and you are all talking about another thing ...

what ds ?

no i didnt get it i want the potential difference in volts no one wants to write the steps

can anyone solve it in steps?

i only studied electromagnetic induction and some electricity is there some law or formula to solve the problem i really appreciate your help i want to know under what topic is that thing

i tried to get the total change in strength -500-400=-900N/C hten tried to change it into volts but i couldnt. and thanks DR sammy

Homework Statement A space probe travels towards a planet measuring the electrostaticpotential as it approches. the electric field strength is -500 N/C at the altitude of 600,000 KM and it decreases steadily until it reaches -400 N/C at 580,000 KM above the planet's surface . find the...
