Answer : The acceleration of the elevator is,
Explanation :
Formula used to calculate the acceleration of the elevator is:
where,
F = force = 844 M
m = mass of man = 70 kg
g = acceleration due to gravity =
a = acceleration of the elevator = ?
Now put all the given values in the above formula, we get:
Thus, the acceleration of the elevator is,
I think the correct answer from the choices listed above is the second option. In Niels Bohr’s model of the atom, electrons move like planets orbiting the sun.
