Find the period of small oscillation of a simple pendulum of length \['\ell '\] if it's point of suspension O moves relative to the earth with a constant acceleration\[\bar{a}\], given \[\ell =30\text{ }cm\]and \[\left| {\bar{a}} \right|=g/2\]the angle between the vectors \[\bar{g}\]and \[\bar{a}\]is\[\beta =120{}^\circ \]. The period (in sec) of oscillation of the pendulum is
