Question
A car when passes through a convex bridge exerts a force
on it which is equal to-Solution
Suppose that the body exerts a force N on the surface when it travels through the convex surface. The forces on the car is mg downwards and N upwards. Hence the total force mg−N will provide the essential centripetal acceleration to the car. ⇒ mg - N = mv2/R ⇒ N= mg- mv2/R
