Your answer is partially correct.
The ammonia molecule NH3 has a permanent electric dipole moment equal to 1.47 D, where 1 D-1 debye unit-3.34 x 10-30 C-m.
Calculate the electric potential in volts due to an ammonia molecule at a point 46.7 nm away along the axis of the dipole. (Set V-0 at
infinity.)
