11No one Trying ???
Please post the complete solutions of the following numericals. I have tried to solve them many ..but unsuccessfully.
1) Two equal +ve point charges are separated by a distance 2a. A point test charge is located in a plane which is normal to the line joining these two charges and midway between them. (a) Calculate the radius r of the circle of symmetry in this plane for which the force on the test charge has a maximum value.(b) what is the direction of the force assuming a positive test charge.
2)a cube of edge a carries a point charge q at each corner.Show that the magnitude of the resultant force on any one of the charge is
F= .261q2εa2

Number 2 is a very weird problem....
See I'm giving u an outline, u can easily figure out it from there as it is simple calculation after that...
Force experienced by q due to another charge q' = qq'/4piepsilonr^2....here force on any 1 charge will be due to all the other charges present, in the cube, get it?
