What happens to the other side of the world during a solar eclipse? During a solar eclipse, the moon covers the sun, creating a shadow onto the earth, right? Well during that event, both the sun and the moon are in the same side of the earth. So what happens to the other side? It's supposed to be night time there but there's no moon?

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?
