Using the method of images, discuss the problem of a point charge q inside a hollow, grounded, conducting sphere of inner radius a. Find, a) the potential inside the sphere; b) the induced surface-charge density; c) the magnitude and direction of the force acting on q. d) Is there any change in the solution if the sphere is kept at a fixed potential V?

Calculate the potential due to a point charge q in the presence of a conducting sphere at constant potential V. Radius of conducting sphere is R. The point charge is situated at a distance b from the center of the sphere (b>R) ( Image charge for a grounded conducting sphere is given ; q' = -(Rq)/b and distance r'= R^(2)/b
Consider a charge Q located a distance D>R away from a grounded conducting sphere, where R is the radius of the sphere. Using the method of images, calculate the magnitude and position of the associated image charge. Determine the induced surface charge density of the sphere. .
The name of the book is introduction to electrodynamics fourth edition for David Griffiths Two point charges, q_1 = -10 mu C and q_2 = +20 mu C, are located along the 2-axis at z = 2 cm and z = 5 cm, respectively. There is a grounded conducting plane at z = 0. You will need to read over the section on image charges very carefully. Use the method of images to write down an expression for the potential...

Only need help with (d) = 0 ( [this point is away from 0] A conducting sphere of radius a is hollow and grounded (V = 0). A particle of charge q is a placed inside at a distance b from the center. We wish to find the potential anywhere inside the sphere. This problem can be solved with the image charge method. The image charge d' should be placed a distance b = from the center, so that the...
