Hello, i was doing my work and am unsure about some of these questions. i am hoping someone here can help me out.
1. Because Earth has an electric field of 150N/C, water droplets can remain stationary in the atmosphere if they are charges. if the avg water droplet is 0.030 mm in diameter, how many electron does it need to remain stationary?
2. it asks to draw the magnetic field lines and trajectories of the negatively charged particles. i know how the field lines go but wont the electrons go in the opposite direction?
thank you for your assistance
