Two semi-infinite grounded conducting planes intersect at 60
degrees. A point charge is situated inside this wedge-shaped
region.
(a) Find image charges to obtain the potential between the
conductors.
(b) Can you use the result of part (a) to obtain the Green function
for the Dirichlet problem between the planes? No explicit
calculation is required; just explain
A point charge +q is at the origin. A spherical
Gaussian surface centered at the origin encloses +q. So
does a cubical surface centered at the origin and with edges
parallel to the axes. Select "True" or "False" for each statement
below.
1. Suppose (for this statement only), that q is moved
from the origin but is still within both the surfaces. The flux
through both surfaces is changed.
2.If the radius of the spherical Gaussian Surface is varied, the...

A point of charge q is placed at the point (-d,0) and a second
point charge of charge 2q is placed
at point (2d,0). a) What is the force on the third charge of charge
-q placed at point (0,d) if d=190nm and q=250nC? b) find the two

Two infinite planes of charge lie parallel to each other and to
the yz plane. One is at x = -2 m and has a surface charge density
of ϝ = -3.2 µC/m2. The other is at x = 3 m and has a surface charge
density of ϝ = 4.0 µC/m2. Find the electric field for the following
locations.
(a) x < -2 m = N/C (i hat)
(b) -2 m < x < 3 m = N/C (i...
A point charge of is at the origin, and a second
point charge of +6.00nC is on the x axis at x=0.800m Find
the magnitude and direction of the electric field at each
of the following points on the x axis
a)x=20.0cm b)x=1.20m c) -20.0cm
so, since its electric field question using e=k*q/r^2 i can
solve this
so, e= (k*q/r^2) + (k*q/r^2)
so, +6.00nC is on the x axis at x=0.800m....
and -4.00nC is at the origin.. so 0.
