I don't know where to even start-this is a high school Physics, not AP, and I have the formulas but I don't know where I find the point charge etc to work with-Any help-thank you

**drwls**, Thursday, April 7, 2011 at 3:57pmRelax. This is pretty easy. Not even AP

The electrical force on an electron at the Earth's surface is

F_e = E*e ,

where

e is the electron charge and E is the field strength they gave you.

The gravitational force on an electron at the same place is

F_g = m_e*g

where m_e is the mass of the electron and g is the acceleration of gravity.

You should know where to look up e, m_e and g.

Compute and compare the two forces.

Thanks for breaking it into smaller steps for me
