A uniform electric field`vecE=3hatk+3hatj` has been switched on. The angular velocity vectorof the dipole when dipole nioment aligns with the electric field is :

A

`sqrt((3sqrt(2Q))/(2ML))(-hatj+hatk)`

B

`sqrt((6sqrt(2Q))/(ML))(-hatj+hatk)`

C

`sqrt((3sqrt(2Q))/(ML))(-hatj-hatk)`

D

`sqrt((3sqrt(2Q))/(ML))(-hatj+hatk)`

A point particle of mass M is attached to one end of a massless rigid non-conducting rod of length L. Another point particle of the same mass is attached to the other end of the rod. The two particles carry charges +q and -q respectively. This arrangement is held in a region of a uniform electric field E such that the rod makes a small angle theta (say of about 5 degree) with the field direction, fig. Find an expression for the minimum time needed for the rod to become parrallel to the field after it is set free.
