Solve the following questions given below:
Question 1: If an electron's position can be measured to an accuracy of 1.80E-8 m, what is the uncertainty in its momentum?
Question 2: Assuming its momentum must be at least equal to its uncertainty, estimate the electron's wavelength.
I need proficient help in the above question.
