Find the Electric Field originating from the disk of radius R and charge Q at the distance z above its centre. Use this result to obtain expression for the electric field at distance ze from the infinite plane. Use opposite side of this page for your solution. Make sure that you include the large diagram with clearly stated variables, angles etc

An electric field can be created by a single charge or a distribution of charges. The electric field a distance r from a point charge q' has magnitude {E}=k\frac{|q'|}{r^2}. The electric field points away from positive charges and toward negative charges. A distribution of charges creates an electric field that can be found by taking the vector sum of the fields created by individual point charges. Note that if a charge q is placed in an electric field created by...

located at (d/2,0,0), another + located at 2. A charge distribution has 3 point charges: + (-d/2.0,0), and a +27 located at (0.0, -d). (a) (3 points) Sketch the distribution below. (b) (3 points) What is tot for this distribution? (c) (4 points) What is the dipole moment, p, of this distribution (including the direction)? (d) (8 points) If you get far away, what is the simplest (non-zero) approximation for the potential V(r.)? To get full credit, you need to...

A-How does the electric field vary as one moves away from a point charge? –the outside of a spherical distribution of charge? -- the inside hollow space of a spherical distribution of charge? –a line of charge? -- far away from a dipole along the perpendicular bisector? -- an infinite sheet of charge? -- inside a capacitor? B-Describe electric field lines from a sphere? –from a flat surface? -- from a pointed object? C- What is the geometric relationship between...

You have four point charges. Their location and charges in Cartesian coordinates are: a positive charge, 2q, located at (a,0,0), another charge -2q located at (-a,0,0), a 3rd charge -q located at (0,0,b), and finally a fourth charge +5q located at (0,0,-b) (a) What is the total charge, and dipole moment, of this distribution of charges? Use the methods of "the multipole expansion" (Griffiths section 3.4.1) to find a simple approximate formula for V(r,0) (in spherical coordinates!) valid at points...

An electric field can be created by a single charge or a distribution of charges. The electric field a distance from a point charge has magnitude E = k|q'|/r^2. The electric field points away from positive charges and toward negative charges. A distribution of charges creates an electric field that can be found by taking the vector sum of the fields created by individual point charges. Note that if a charge is placed in an electric field created by q',...

2.1 In this problem we find the electric field on the axis of a
cylindrical shell of radius R and height h when the cylinder is
uniformly charged with surface charge density . The axis of the
cylinder is set on the z-axis and the bottom of the cylinder is set
z = 0 and top z = h. We designate the point P where we measure the
electric field to be z = z0. (See figure.) You will use...
