Electrons and Gravity
Science brain teasers require understanding of the physical or biological world and the laws that govern it.
What will happen if we keep a bucket beneath a current-carrying wire and cut the wire? Will the electrons fall into the bucket?
Assume that the wire doesn't actually touch the bucket after it is cut.
Answer
The force of gravity is much much less than electrostatic force so no electron will fall into the bucket.
Remember, this is not water.

| Nice job! It was rather easy, but it's really cool! Keep it up! |

| This one was pretty cool one and it made sense even though it was pretty easy. I've been learning about electrons and gravity lately so it took my interest. |

| Whether the wire touches the bucket after it is cut is irrelevant. Electrons will not "flow into the bucket" under any circumstance. They will either flow through the bucket if it's a conductive material or cease to flow at all as the current ceases to flow. |

| Well yeah, air pressure keeps the electrons from dribbling out of the wire! ;) |

| profnick, please tell me the air pressure thing was a joke. Wait, are you actually a professor? Uh oh, poor students. |
