To $F_{the force}$

Classical Mechanics Level 2

Three identical cars A, B and C are moving at the same speed on three bridges. The car A goes on a plane bridge, B on a bridge convex upward and C goes on a bridge concave upward. Let $F_{A}$ , $F_{B}$ and $F_{C}$ , be the normal forces exerted by the cars on the bridges when they are at the middle of bridges.

Then which of the following is true?

F_{A}

is maximum of the three forces.

F_{B}

is maximum of the three forces.

F_{A}

F_{B}

F_{C}

F_{C}

is maximum of the three forces.
