Question

A car when passes through a convex bridge exerts a force on it which is equal to :- Mv2 Mg + r O Mv2 r O MO 0 Mg - Mv2/r​

Answer 1

Answer:

Mg−rMv2

Explaining =

Mg−rMv2

The forces on the car is mg downwards and N upwards.

Hence the total force mg−N will provide the essential centripital acceleration to the car.

Hence mg−N=Rmv2

Hence N=mg−Rmv2
