GATE 2021 : Electromagnetic Theory Rapid Quiz-1 (App update required to attempt this test)

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

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

An E-field is given by  = 4x â_x+2 â_y V/m. Then the work required in Joules to move a unit positive charge along the curve xy=4 from (2,2) to (4,1) is

Suppose we have a radiating field given by:

A/m, and it is in free space.

Now, determine the value of magnetic flux (in weber) that crosses the surface which is defined in the area given by: 0 and 0.

A filamentary conductor is formed into an equilateral triangle of side 2m that carries a current of 4A as shown in figure. The magnetic field intensity at the center of the triangle will be ….. A/m in a_z direction.
