conceptual q (based on q 1.43)

Postby nikitasridhar_1b » Wed May 09, 2018 1:11 am

sometimes the uncertainty is not given and only the position is given (like in 1.43). how can we incorporate this into the equation when this is the actual momentum value, not the momentum value multiplied by the uncertainty.

the uncertainty is change in position so delta x. if you know delta x you can solve for delta v which is uncertainty in velocity.

since we are solving for an electron, we know its mass, and we are given position so we can find v based on the equation
