What is the empirical relationship for the rate of neck growth when a sphere is in contact with a flat surface?

Rate of neck growth ∝ \(t^{\frac{2}{7}}\)

Rate of neck growth ∝ \(t^{\frac{1}{6}}\)

Rate of neck growth ∝ \(t^{\frac{1}{7}}\)

Rate of neck growth ∝ \(t^{\frac{2}{7}}\)

Rate of neck growth ∝ \(t^{\frac{1}{8}}\)
