JEE MainPhysicsRotational MotionMCQ+4 / −1
An electric dipole is formed by two equal and opposite charges q with separation d. The charges have same mass m. It is kept in a uniform electric field E. If it is slightly rotated from its equilibrium orientation, then its angular frequency ω\omegaω is :-

  2. B
    qE2md\sqrt {{{qE} \over {2md}}}2mdqE​​
  3. C
    qE−2md\sqrt {{{qE} \over {-2md}}}−2mdqE​​
  4. D
