The reaction of the floor on an object placed on the floor of an elevator is maximum when elevator
- A is stationary
- B accelerates upwards
- C cable snaps and it falls freely towards the Earth
- D accelerates downwards
Answer & Solution
Correct Answer
(B) accelerates upwards
Step-by-step Solution
Detailed explanation
The reaction of the floor on an object placed on the floor of an elevator is maximum, when the elevator accelerates upwards. In this case, normal reaction on it is \[ N=m(g+a) \] where, \(m=\) mass of object, \(g\) = gravitational acceleration and \(\quad a=\) acceleration of…
