How much work is required to stop an electron

The're, um according toa work. Kinetic energy theory. Um, W is equal to the attack. That is wagon is equal to change in kinetic energy. And what is the meaning? Off change. The meaning off changes final minus initial. So here work is required. Toe final Kinetic energy minus initial kinetic energy final kinetic energy. We know the formula of kinetic energy. It is half MV square. So final kinetic energy we must, right? Uh huh. Of am we finally Squire minus how and me We initial square in question This massive electron is they noted as M so we can write.

Ah mm. We finally Squire minus have I am we initially square now we need to put the values. So if we put the values here, we finally zero so it will become zero minus half the value off masses given 9. Holy Squire. So after solving this expression, we will get minus 5. Jewell, I hope you understood the solution.

You will need the same number of protons. The distance require to stop a car varies directly as the square of its speed.

If feet are required to stop a car traveling 60 miles per hour, how many feet are required to stop a car traveling 96 miles per hour! The "work function", or the minimum energy needed to eject an electron from the metal, can be expressed in several different ways. As stated on the applet page, sodium has a work function of 2. In class, we discussed how to. Look up the mass of the electron and call it m.
