Distence between. their surfacel ( =12 R-R-2 R ) since [ begin{array}{l} p alpha operatorname{man} a alpha max end{array} ] Distance d acclesation So we can conite [ begin{array}{l} frac{a_{1}}{a_{2}}=frac{m}{5 m}=frac{91}{s_{2}} frac{s_{1}}{s_{2}}=frac{1}{s} s_{1}=s_{2}-0 s_{1}+s_{2}=9 R-2 end{array} ] on soluing thene equations [ S_{1}=1-s R ] ( S_{2}=7-5 R rightarrow ) dustance forcel by Smoller boit Since Smoller ball hawe mose acch in seme hone interval, smoller boll will cover more distence.
