The radius of the wire in a coaxial cable is 0.65 mm and the inner radius of the coaxial conducting cylinder is 1.45 mm. Assuming that there is vacuum between the
wire and the cylinder, calculate the capacitance of a 1.5 m length of the cable.
A long, straight wire of radius 5.0 mm carries a current of 20A. i) Calculate the magnetic field at the surface of the wire, and ii) calculate the perpendicular distance, from the axis of the wire, at which the magnitude of magnetic field will be half of
its value at the wire surface.
Show that, if there are any unbalanced, static charges on an isolated conductor, they
must reside on its surface.
The magnitude of work done in taking a unit positive charge in electric field E from point A to point B is given by:
Show that the value of the line integral of the electric field (right hand side of the above equation) does not depend on the path taken to move the unit positive charge
from point A to B.
State and explain the boundary condition for the displacement vector D at the
boundary separating two dielectric media.
Calculate the ratio of the electrostatic force and the gravitational force exerted by protons on each other.
Using Maxwell’s equations in free space, derive the wave equation for the
electric field vector. Obtain the conditions under which the following time varying electric and magnetic fields satisfy Maxwell’s equations in vacuum with no source charges or currents:
E = kˆ E0 sin ( y − vt)
B = ˆi B0 sin ( y − vt)
where E0 and B0 are constant.
