E all depend on electricity. Most electricity is created by electromagnetic generators at large power plants and distributed through an electric grid. The electric grid in the United States is interconnected and includes more than 400,000 miles of electric transmission lines. However, the grid has not been well maintained, and the number and severity of power outages has been rising over the past decade. Because the grid is interconnected, a severe power outage in one area can quickly spread to other areas. How long could you survive without electricity? What parts of your life would be affected by loss of electricity? Should you prepare for an electricity outage, and if so, how would you prepare? What backup system could your family or community install to generate limited amounts of electricity during an outage? How does this system create an electric force field and generate electric current?

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,?
