charge and capacitance of the cylindrical capacitor
A cylindrical capacitor has an inner conductor with a radius of 1.4mm and an outer conductor with a radius of 3.9mm. Both conductors are separated by a vacuum, and the entire capacitor has a length of 2.4m
1) What is the capacitance per unit length?
2) The potential of the inner conductor relative to that of the outer conductor is 310mV. Find the charge (magnitude & sign) on both conductors.
