The mass of an electron is difficult to find because of the Heisenberg Uncertainty Principle. Either a particle's position or direction can be known, and the more precisely one is measured, the other is subject to more possible variation.

How do you find the relative uncertainty in the mass of the electron?

To find the relative uncertainty in the mass of the electron, you would typically determine the absolute uncertainty in the measurement of the electron's mass and then divide it by the measured value of the electron's mass. Finally, multiplying by 100 will give you the relative uncertainty as a percentage.

Is The Mass Of An Electron Is Equal To The Mass Of A Neutrons?

No. The mass of a neutron is far, far, far greater than the mass of an electron. In fact, the mass of a neutron is approximately about 1840 times greater than the mass of an electron. The particle that has exactly the same mass as an electron is its antiparticle, the positron.


What is the tiny subatomic particles related to the electron that has no electric charge and little mass?

The tiny subatomic particle related to the electron that has no electric charge and little mass is the neutrino. Neutrinos are extremely difficult to detect due to their neutral charge and low interaction with matter.
