Calculate the potential energy of a charge +6nC placed at 0.07m from a charge +76 x10^-6C. If the same charge(+6nC) is now at 0.07m from a charge -88 x10^-6C, find its new potential energy.   

What must be the distance between point charge q1 = 26 uC and point charge q2 =-47 uC for the electrostatic force between them to have a magnitude of 5.70 N?

1. Determine the peak frequency deviation for a FM modulator with a deviation sensitivity of 12 kHz/V  and a peak modulating signal of 9V.

The following region of space has constant charge density 𝜌. Assume that the region is infinite in the x-y plane and of height d (see Figure below).

(a) Determine the electric field inside and outside the charged region.

(b) Given that d is negligible, use Coulombs law to find the electric field above and below the z-axis.

Consider an infinite slab of thickness d and uniform volume charge density ρ. This is essentially an infinite plane with a non-negligible thickness. The planar symmetry involves z to -z reflection symmetry, as well as infinite in the x-y plane. Use Gauss law to find the electric field produced outside the slab and inside the slab .

A cuboid has a region of space that has constant charge density, p. Assume that the region is infinite in the x-y plane and of height d. Given that d is negligible, use Coulomb's law to find the electric field above and below the z-axis.
