← An isolated metal ball has a diameter of 70 cm. How much charge must be put on it to raise its potential to 5500 V?A dielectric slab of constant 3.5 is placed in a field at right angles to its faces. What is the ratio of the bound charge on each unit of area of a face to the free charge on each unit of area of the plates that make the field? →
