Don't know where to go Get stuck at every corner. Here it is "A small droplet of oil of 50^10*-6m radius is sitting inside of an electric field 500^10*3 N/C which is pointing straight up. What must be the charge on the oil droplet so that the electrostatic force cancels out due to gravity? The density of oil is 800kg kg/m^3 I don't know where I am going with this. I used E=kQ/r^2 knowing E as 500^10*3 then igured Q as 138.86^10*-15C. I s this even close. Thanks "Learning Never Stops"
