Use E = F/q to solve the following problem:
Ernie pulls his wool sweater over his head, which charges his body as the sweater rubs against his cotton shirt. What is the electric field at a location where a 1.60 x 10^-19 C piece of lint experiences a force of 3.2 x 10^-9 N as it floats near Ernie?

unklerhaukus · Answer

$$\vec E=\frac{ \vec F}C$$$$\vec E=\frac{3.2\times10^{-9}\text N }{1.60\times 10^{-9} \text C }$$

anonymous · Answer

$$E=F/Q$$

E=(3.2*10^-9)/(1.60*10^-19)

 =2*10^10 volt/metre  or newton/coulomb
