According to Millikan's oil drop experiment, the magnitude of electrical charge \( q \) on any droplet is always an integral multiple of the fundamental electrical charge \( e \), which is expressed as:

1. \( q = n/e \text{ where } n = 1, 2, 3 \dots \)
2. \( q = n^2 e \text{ where } n = 1, 2, 3 \dots \)
3. \( q = e / n^2 \text{ where } n = 1, 2, 3 \dots \)
4. \( q = n e \text{ where } n = 1, 2, 3 \dots \)
