A short dipole has dipole moment 10 -2 C m along negative Z axis. It is kept in an electric field along positive Z axis which uniformly increases at the rate of 10^3 N/C per metre. Find the net force and torque acting on the dipole. |

Answer» A dipole of dipole MOMENT p is placed in a NON uniform electric field along x axis. electric field is increasing at the rate of 1v/m then the force on dipole is...Answer : force on dipole = p explanation : given, A dipole of dipole moment p is placed in a non-unifrom electric field along x - axis. Let US CONSIDER that E(x) is electric field along x-axis. now, electric field is increasing at the rate of 1 V/m . i.e., dE(x)/dx = 1V/m.we know, force due to dipole is given by, F = dipole moment × electric field gradient = p × dE(x)/dx = p × 1 = p Hence, force on the dipole should be p ✔ |
