Heat And Thermodynamics

A system consists of two types of gas molecules A and B having same number density 2 \(\times\) 10²⁵/m³. The diameter of A and B are 10 \(\mathop A\limits^o\) and 5 \(\mathop A\limits^o\) respectively. They suffer collision at room temperature. The ratio of average distance covered by the molecule A to that of B between two successive collision is ____________ \(\times\) 10^\(-\)2
