A $550\;N$ physics student stands on a bathroom scale in an elevator. As the elevator starts moving the scale reads $450\;N$. Draw a free body diagram of the problem and find the magnitude and direction of the acceleration of the elevator.
Given,
Weight of the body $(w = mg = 550\;N)$
Normal Reaction $(R) = 450\;N$
Acceleration $(a) = \;?$
We have,
Here, the weight of the body is greater than the normal reaction, hence the elevator is moving downward with acceleration $(a)$. Then for downward motion,
where is the diagram??
