In case of S.H.M. the period of oscillation (T), is given by

T = 2ω/π²

T = 2π/ω

T = 2/ω

T = π/2ω

T = 2ω/π²

T = 2π/ω

T = 2/ω

T = π/2ω

The centre of gravity of the trapezium as shown in below figure from the side is at a distance of

(h/3) × [(b + 2a)/(b + a)]

(h/2) × [(2b + a)/(b + a)]

(h/2) × [(b + 2a)/(b + a)]

(h/3) × [(2b + a)/(b + a)]

(h/3) × [(b + 2a)/(b + a)]

(h/2) × [(2b + a)/(b + a)]

(h/2) × [(b + 2a)/(b + a)]
