The diagram depicts two horizontal metal plates arranged parallel to each other. A potential difference $V$ exists across the plates. A tiny charged liquid droplet, positioned halfway between the plates, remains stationary because its weight is balanced by the electric force acting on it. The acceleration of free fall is $g$ and the electric field strength is $E$. What is the sign of the charge on the droplet, and what is the charge-to-mass ratio of the droplet?
- Anegative, $\frac{E}{g}$
- Bnegative, $\frac{g}{E}$
- Cpositive, $\frac{E}{g}$
- Dpositive, $\frac{g}{E}$
