The given figure shows three identical carom boards labeled I, II, and III. Sand particles have been poured on board I and oil has been poured on board II.Equal forces are applied on three identical pucks on the three carom boards such that their speeds on the three carom boards are \[{{v}_{1}},{{v}_{2}}\]and \[{{v}_{3}}\] respectively. The relation among the speeds of the pucks on the three carom boards is

A.  \[{{v}_{1}}>{{v}_{3}}>{{v}_{2}}\]                             
B.  \[{{v}_{1}}<{{v}_{3}}<{{v}_{2}}\]
C.  \[{{v}_{1}}>{{v}_{2}}>{{v}_{3}}\]             
D.  \[{{v}_{1}}<{{v}_{2}}<{{v}_{3}}\]
Answer» C.  \[{{v}_{1}}>{{v}_{2}}>{{v}_{3}}\]
