A car moves on a concave bridge of radius R then the maximum reaction force on the car will be:
[ let the mass of the car be m]
mg
As we learn
Reaction of Road on Car -
Centripetal force =
Reaction R =
R = reaction
V=velocity
r = radius
- wherein
It is a case when car moves on a concave bridge.
maximum reactor will be at lowest point of bridge ,so
