Q1

An electric dipole of mass m, charge q, and length l is placed in a uniform electric field \(\vec{E}={E}_{0}\overset{^}{i}\). When the dipole is rotated slightly from its equilibrium position and released, the time period of its oscillations will be:

a

\(\frac{1}{2\pi }\sqrt{\frac{2ml}{q{E}_{0}}}\)

b

\(2\pi \sqrt{\frac{ml}{q{E}_{0}}}\)

c

\(2\pi \sqrt{\frac{ml}{2q{E}_{0}}}\)

d

\(\frac{1}{2\pi }\sqrt{\frac{ml}{2q{E}_{0}}}\)
