All Electric Fields Formula in 1 Minutes #shorts - Saurabh Maurya - IIT BHU

The frequency of oscillation of the magnet in an oscillation magnetometer in the earth's magnetic field is 40 oscillations per minute. A short bar magnet is placed to the north of the magnetometer, at a separation of 20cm from the oscillating magnet, with its north pole pointing towards north (figure). The frequency of oscillation is found to increase to 60 oscillations per minute. Calculate the magnetic moment of this short bar magnet. Horizonatl component of the earth's magnetic field is 24 muT .

Two charged particle having masses in the ratio 2:3 and charges in the ratio 1:2 are released from rest in a uniform electric field.After a time 1 minute their K.E.will be in the ratio of

A short electric dipole of dipole moment P is placed in stable equilibrium in uniform electric field E as shown in the figure. The work done by the external agent to rotate the dipole slowly up to its unstable equilibrium will be

An isolated conducting sheet of area A and carrying a charge Q is placed in a uniform electric field E, such that the electric field is perpendicular to the sheet and covers all the sheet. Find out the charges appearing on its two surfaces.
