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© BrainMass Inc. brainmass.com September 18, 2018, 12:27 pm ad1c9bdddf
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.
