If the dipole of moment 2.57 × 10−17 Cm is placed into an electric field of magnitude 3.0 × 104 N/C such that the fields lines are aligned at 30∘ with the line joining P to the dipole, what torque acts on the dipole?
Two point dipoles of dipole moment p1 and p2 are at a distance x from each other and . The force between the dipoles is:
In the figure, the net electric flux through the area when the system is in air. On immersing the system in water the net electric flux through the area
A hollow cylinder has a charge coulomb within it. If is the electric flux in units of voltmeter associated with the curved surface , the flux linked with the plane surface in units of voltmeter will be
