Question 1

A point P is specified in Cartesian coordinate system as P(1,2,3). What will be the points in Cylindrical coordinate system.

Question 2

Two concentric spherical surfaces with r = 2 m and r = 10 m having uniform surface charge densities 40 nC/m2 and 10 nC/m2 respectively. The radial electric flux density at r = 4 m is

Question 3

The velocity vector is given as . The divergence of this velocity vector at (1,1,1)

Question 4
