Three identical dipoles are arranged as shown below. What will be the net electric field at `P(k=1/(4pi epsilon_(0)))`

Three infinitely long charge sheets are placed as shown below. Find the electric field at the pint P.

The correct formula for potential energy in the electric field of an electrical dipole body is, when the angle of the electric dipole is theta with the electric field (k=(1)/( 4pi in_(0)))

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

What is the value of (1)/(4pi epsilon_(0)) in SI unit?

What is the value of 1/4pi epsilon_0 ?

A dipole of dipole moment P is kept at the centre of a ring of radius R and charge Q. If the dipole lies along the axis of the ring. Electric force on the ring due to the dipole is : (K = (1)/(4pi epsilon_(0)))
