A vehicle weighing w kg is to run on a circular curve of radius r. If the height of its centre of gravity above the road level is h and the distance between the centres of wheels is 2a, the maximum velocity, in order to avoid over turning, will be

\(\frac { gra } { h} \)

\( \sqrt\frac { gra } { h } \)
