Mass of an electron

Postby Isabelle Bautista 3H » Wed Oct 11, 2017 8:54 pm

Do we keep the mass of an electron in kg when solving photoelectric effect equation problems?

Yes, mass is measured in kilograms for the photoelectric effect equation problems. This is indicated in Example 1.5 for analyzing the photoelectric effect in the textbook.

Yes! This gives you joules when you calculate the Kinetic Energy(KE)!
Hope this helps!

Yes, for the mass of an electron use kg

Equation: E(kinetic)=(1/2)me-(ve-)2

Units: Joules = kg (m2/s2)
