A capacitor consists of two air spaced concentric cylinders.the outer radius b is fixed and inner radius a. If breakdown of air occurs at field strength greater than Eb. show that inner cylinder should have 1) radius a=b/e if the potential of inner cylinder is to be maximum 2) radius a=b/√e if energy per unit length of the system is to be maximum
