to find @ the angle of banking:
the eqn for eqbm of vehicle in absense of friction: (v^2/r)cos@=mgsin@
tan@=1/2
now friction comes in to the pic
friction can act upward or downwards so 2 cases
2 move neithe up or down,eqbm eqn give:
(mv^2/r)cos@ +(or - ) (mgcos@+(mv^2/r)sin@)=mgsin@
we get v^2/r=7 or 3

hence v=root(60) or root(140)-edited after the correction im gettimg same as varun
the value of N is N=mgcos@ +(mv^2/r)sin@
