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 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 2q and 8q are placed at a distance r apart. Where should a third charge -q be placed between them so that the electrical potential energy of the system is a minimum

Two point charges 2q and 8q are placed at a distance r apart. Where should a third charge -q be placed between them so that the electrical potential energy of the system is a minimum

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 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 charges -q each are fixed separated by distance 2d. A third charge q of mass m placed at the midpoint is displaced slightly by x (x

Two free charges q and 4q are placed at a distance d apart A third charge Q is placed between them at a distance x from charge q such that the system is in equilibrium. Then magnitude of third charge and postion,
