1-a) Does an electrically neutral particle that has mass interact with an electric field? b) Does a charged particle interact with a gravitational field?
2- Can electrical and gravitational fields exist in the same place at the same time?
3- If you know the electric field E at some location, how can you determine the magnitude and direction of the electric force exerted by that field on an object carrying a charge q and placed at that location?
4- A water droplet carrying a positive charge is released from rest in a uniform horizontal electric field near Earth's surface. The horizontal electric force is comparable in magnitude to the gravitational force exerted by the Earth. Describe the droplet's trajectory.
