An electric dipole is made up of two particles, one having charge +1 μC and mass 1 kg and the other with charge −1 μC and mass 1 kg separated by distance 1 m. It is in equilibrium in a uniform electric field of 20×103 V/m. If the dipole is deflected through an angle 2∘, then time taken by it to come again at equilibrium position is

1.	An electric dipole is made up of two particles, one having charge +1 μC and mass 1 kg and the other with charge −1 μC and mass 1 kg separated by distance 1 m. It is in equilibrium in a uniform electric field of 20×103 V/m. If the dipole is deflected through an angle 2∘, then time taken by it to come again at equilibrium position is
Answer» An electric dipole is made up of two particles, one having charge $+ 1 μ C$ and mass $1 kg$ and the other with charge $- 1 μ C$ and mass $1 kg$ separated by distance $1 m$ . It is in equilibrium in a uniform electric field of $20 \times 10^{3} V / m$ . If the dipole is deflected through an angle $2^{\circ}$ , then time taken by it to come again at equilibrium position is
