Two cars are moving on a banked circular path of radius $8 \mathrm{~m}$ having angle of banking $45^{\circ}$. If the coefficients of static friction between the road and the tyres of the two cars are 0.5 and 0.4 respectively, then the ratio of maximum permissible speeds of the cars to avoid slipping is
  1. $\sqrt{7}: \sqrt{5}$
  2. $\sqrt{9}: \sqrt{7}$
  3. $\sqrt{11}: \sqrt{7}$
  4. $\sqrt{13}: \sqrt{11}$
