A charged object has a mass of 9.11E-31 kg and a charge of 1.602E-19coul. Calculate the strength of the electric field that would provide a force to the weight of the charged object.

 

This is what I have so far

 

F = Ee/m 1.602E-19 * 1.6 E-19 / 9.11E-31 = 2.81E-8 N

 

is this correct

I'm actually not sure what that question is asking. "Calculate the strength of the electric field that would provide a force to the weight of the charged object."

 

Find the objects weight (m*g).

 

Then find the strength of an electric field which will provide that force??

Your units don't work, so the answer can't be right.

 

You want an electrostatic force equal to the weight.

 

F=qE is the electrostatic force

 

F=mg is the weight.

 

Set them equal and solve for E (note that there is no need to solve for F)
