Electric potential due to a dipole at a position `vec r` from its centre is: where `(K = 1/(4pi epsilon_0)`

The electric field due to a dipole at a distnce r from its centre is proportional to

What are the units of K = 1/(4 pi epsilon_0) ?

In the previous question assume that the electrostatic potential is zero at an infinite distance from the spherical shell. The electrostatic potential at a distance R (a lt R lt b) from the centre of the shell is where (K=1/(4pi epsilon_(0)))
