Q. No.There exists a uniform electric field of \(20 \hat{i}~\text{N/C}.\) A dipole of dipole moment \(|\vec{p}|=15~\text {C-m}\) is placed at angle \(30^\circ\) with the electric field. The torque on the dipole is:
1. \(250~\text{N-m}\)
2. \(150~\text{N-m}\)
3. \(200~\text{N-m}\)
4. \(100~\text{N-m}\)
1. \(250~\text{N-m}\)
2. \(150~\text{N-m}\)
3. \(200~\text{N-m}\)
4. \(100~\text{N-m}\)
