A disk with radius R has uniform surface charge density "sigma". a) by regarding the disk as a sereis of thin concentric rings, calculate the electric potential V at a point on the disk's axis distance x from thecentere of the disk.Assume that the potential is zero at infinity. b) Calculate -dV/dx.show that the result agrees with the expression for Ex
