# Why are the passengers in the upper deck of the double-decker bus not allowed to stand?(A) This ensures that the center of gravity of the system may not rise up and the bus may not to be toppled due to unstable equilibrium(B) This ensures smaller centripetal force, thus helping the driver to negotiate the roundabouts properly(C) If the passengers are in standing position, they may start oscillating due to jerks and there is a possibility of resonance, causing the bus to be toppled(D) This is just for the safety reason

In a double-decker bus, when a person stands in the upper deck of a bus, the center of gravity of a person is also raised. Any angular motion that the bus makes will be experienced by the person as linear motion. Let’s say that there is an angular acceleration $\alpha$ . The linear acceleration experienced by the person is going to be $a = \alpha .r$ which is more when the person is standing since the r is more. This means that the passenger can fall and get hurt!
