A semi-circular ring of mass m and radius R with linear charge ilensity `lambda`, hinged at its centre. is placed in a uniform electric field as shown in the figure `-1.451`. Ifthe ring is slightly rotated about O and released find the time period (in sec) of oscillation. Take `m = 8 kg, lambda= 2 C//m` and `E = 2 N//c`. Assume that coil is rotated in its own plane
