Unformatted text preview: potential functions that can be used to determine potential at any point inside or outside the sphere. 4. The potential on a very long (assume inﬁnite) cylinder of radius R is given by V sin(3 φ ). The zaxis lies along the axis of the cylinder. Determine potential inside and outside the cylinder. 5. The potential on a very long (assume inﬁnite) cylinder of radius R is given by V cos 3 φ . The zaxis lies along the axis of the cylinder. Determine potential inside and outside the cylinder. Hint: cos 3 φ = 1 2 cos φ (cos2 φ + 1) = h 1 2 cos φ + 1 4 cos φcos3 φ i...
