Question: the charge of 81 nc is at the point xy...
The charge of 81 nC is at the point xy (0 cm, 2.0 cm) and the
charge at -81 nC (0cm, -2.0 cm). Selecting the zero point of the
potential from infinitely far from the reserves.
a)Determine the dipole moment of the dipole formed by the system
b)Determine the potential with a positive y-axis at r = 6.0 cm from the origin.
c)Determine the potential on the x-axis at r = 6.0 cm from the origin.
d)Determine the potential at r = 6.0 cm from the origin at an angle of 45∘ upwards from the x-axis.
