Electric Charges, Electric Forces and Electric Fields

AI Thread Summary
An object with a net charge of 24 x 10^-6 Coulombs is placed in a vertical electric field of 610 N/C and is floating, indicating that the electric force equals the gravitational force. To find the mass, the electric force can be calculated using the formula E = F/q, where E is the electric field strength. The gravitational force is given by F = mg, where g is the acceleration due to gravity (9.8 m/s²). By equating the electric force to the gravitational force, the mass of the object can be determined. Further questions may arise as the problem-solving process continues.

Homework Statement



An object with a net charge of 24 x 10^-6 Coulombs is placed in a uniform electric field of 610 N/C, directed vertically. What is the mass of this object if it floats in this electric field?

Homework Equations



Felectric = kC (q*q/r^2)
Electric Field= kC (q/r^2)
E= Felectric/q
F=ma

The Attempt at a Solution



I know I need to use F=ma, but I do not know the acceleration. I don't know how to solve this
 
Physics news on Phys.org
Which formula can be used to find the strength of the electric force due to the field?
 
Electric field = Electric force/ q (charge of object)
 
(Electric field equals the electric force divided by the charge of the object)
 
Once the electric force is calculated, it must be equal to the gravitational force since the charge is floating. What formula is used to calculate the gravitational force acting on a mass?
 
F= mg
 
Force of gravity = mass x 9.8
 
Bingo
 
Wow thanks! haha I may have some more questions soon too :)
