Two point charges q each are fixed at (a,0) and (-a,0). A third charge Q is placed at origin. Electrons potential energy of the system will

Two equal charges q are placed at a distance of 2a and a third charge -2q is placed at the midpoint. The potential energy of the system is

The charges q each are placed at a distance 2a and a third charge -2q is placed at the mid point. The P.E. of the system is

Two positive point charges , each Q , are fixed at separation d . A third charge q is placed in the middle. Describe the equilibrium of the third charge.

Two charges of equal magnitude q are placed in air at a distance 2a apart and third charge -2q is placed at mid-point . The potential energy of the system is (epsi_(0) = permittivity of free space)

Two charges of equal magnitude q are placed in air at a distance 2a apart and third charge -2q is placed at mid-point . The potential energy of the system is (epsi_(0) = permittivity of free space)

Two point charges +q and -q are held fixed at (-a,0) and (a,0) respectively of a x-y coordinate system then

Two charges -q each are separated by dsitance 2d. A third charge +q is kept at mid-point O. find potential energy of +q as function of small distance x from 0 due to -q charges. Sketch PE Vs/x and convince yourself that the charge at 0 is in an unstable equilibrium.
