1. The problem statement, all variables and given/known data
One-hundred punctual charges equal 3uC (so Q1=3(micro)C ,Q2=3uC... Q100=3uC stand on a circle with radius r=120cm and they are equable .Find the electric field in the center of the circle and the potential in the center of the circle potencialin . How will potential changes if the charges stand on a circle with radius r1=r/2?
2. Relevant equations
3. The attempt at a solution
I dont know the solution but i tried to find the potential if the circle radius is r/2
i think the potential will be 2 times bigger if the radius is r/2.
please help, i need the solution for tomorow.
I just need the start .. the formula.. i can do calculations by myself
and sorry for my english.
