An alpha particle (the nucleus of a helium atom) has a mass of 6.64x10-27kg and a charge of +2e. What are the (a)magnitude and (b)direction of the electric field that will balance the gravitational force on the particle?
I need to know the step by step setup and answer for this problem given the above information. thank you
Hello and thank you for posting your question to Brainmass.
The gravitational force on the particle is simply its weight Mg:
W = Mg
The electric force on charge q due to the electric field E is:
For balance these two ...
The solution explains how to find teh electric field from force balance considerations.
