Problem-6
The electric field at a point P, expressed in the cylindrical coordinate system is given by,

Find the value of divergence of the field if the location of the point P is given by (1, 2, 3) m in Cartesian coordinates.
Solution
Here,
âˆ´
For the electric field, , the divergence in cylindrical coordinates is given as,

Hence, the divergence of the field at the point P is given as,
