MHT CET 2026 Physics question
An electric dipole of length 3cm is placed with its axis making an angle of with a uniform electric field of 5 x N/C. It experiences a torque of Nm. The magnitude of charge on the dipole is ()
Answer: (B)
Solution
Torque on a dipole , where the dipole length cm m. So \dfrac{τ}{(2l)E\sinθ}\dfrac{9\sqrt{3}}{0.03 × 5×10^4 × \frac{\sqrt{3}}{2}}$ =
