A system of two identical rods (L-shaped) of mass `m` and length `l` are resting on a peg `P` as shown in the figure. If the system is displaced in its plane by a small angle `theta`,find the period of oscillations:
A. `2pisqrt((sqrt(2l))/(3g))`
B. `2pisqrt((2sqrt(2l))/(3g))`
C. `2pisqrt((2l)/(3g))`
D. `3pisqrt((l)/(3g))`
