Assuming no influence of gravity and a restoring force dependent only on surface tension, the period of oscillation t [T] will depend  only on surface tension ? [MT-2], density ? [ML-3], and diameter [L] .        
Answer:    M0 L0 T = [MT-2] a [ ML-3] b [L]c
So , equation will be t = sqrt( (density * (diameter)3) /  surface tension))
