Physics Question from JEE Main 2025 · 23 January, Shift 2

Two point charges −4 μC-4 \, \mu C and 4 μC4 \, \mu C, constituting an electric dipole, are placed at (−9,0,0) cm(-9, 0, 0) \, cm and (9,0,0) cm(9, 0, 0) \, cm in a uniform electric field of strength 104 N/C10^4 \, N/C. The work done on the dipole in rotating it from the equilibrium through 180∘180^\circ is:

  • A

    14.4 mJ14.4 \, mJ

  • B
