The length and mass of the arm are Larm = X1 = 50 cm and Marm = 0.3 kg, X2 = 15 cm, and the mass of the object is MObject = 0.25
kg. For this problem you may assume that the hook at the end of the arm is massless and the gravitational constant can be approximated as g = 10 m/s2 Develop a symbolic expression for the torque required by the motor to lift the object off of the sand.

Answer:
Explanation:
Given that,
The uncertainty in the position of an electron along the x-axis is,
We need to find the east uncertainty in any simultaneous measurement of the momentum component of this electron.
We know that the Heisenberg's uncertainty principle gives the relation between the uncertainty in position and the momentum of electron as :
Putting all the values, we get :
So, the momentum component of this electrons is greater than .
