Q. No.An electric dipole is place at an angle of \(30^{\circ}\) with an electric field intensity \(2\times10^{5}~\text{N/C}\). It experiences a torque equal to \(4~\text{N-m}\). The charge on the dipole, if the dipole length is \(2~\text{cm}\), is:
1. \(8~\text{mC}\)
2. \(2~\text{mC}\)
3. \(5~\text{mC}\)
4. \(7~\mu\text{C}\)
1. \(8~\text{mC}\)
2. \(2~\text{mC}\)
3. \(5~\text{mC}\)
4. \(7~\mu\text{C}\)
