101. (a) The charge on every part of the ring is the same distance from any point P on the axis. This distance is rz R =+ 22 , where R is the radius of the ring and z is the distance from the center of the ring to P . The electric potential at P is V dq r dq zR dq q == + = + = + z z z 1 4 1 4 1 4 11 4 00 0 0 ππ π π εε ε . (b) The electric field is along the axis and its component is given by
