Making use of the formulation and the soulution of the foregoingproblem, findthemagnitudefo the force exertedby the charges bound on the surfaceof the dielectricon the pointcharge q. |

Answer» Solution :The force on the POINT CHAGRE `q` is due to thebound chagres. This can be calculated from the field at thischarge after extracing out the SELF field. This image field is `E_("image") = (epsilon -1)/(epsilon +1) (q)/(4pi epsilon_(0) (2L)^(2))` Thus, `F = (epsilon - 1)/(epsilon +1) (q^(2))/(16pi epsilon_(0) l^(2))` |
