On dry road, the maximum speed of a vehicle along a circular path is ' V '. When the road becomes wet, maximum speed becomes V 2 . If coefficient of friction of dry road is ' ' then that of wet road is

Step-by-step solution

The equation for maximum velocity is V = rg When the road becomes wet the equation becomes V 2 = ^ rg Dividing equation (i) with equation (ii), aligned & V V & = rg ^ rg 2 & = ^ ^ & = 4 aligned
