Imagine this problem given to us, who are not even physics majors and the professor even told us that it wasn’t even a difficult problem. Sheeesh!
>> A cylindrical block of length l and of mass m is placed in a ramp of angle theta. A magnetic field B is applied on the ramp with the upward direction. The cylinder has 10 loops of wires surrounding it. Question: How much current i should be applied to the wires so that the cylindrical block will not slide down or roll?
Wow.. O.o How’s that for a question? After that, we were given an even more difficult question that is so difficult that I can’t even type it here coz it really sucks.. Gosh, even the teacher has some, let’s say, personal cruel intentions to us for a known obvious reason…
Well anyway, if I get a job in the near future, I’ll make sure it doesn’t have anything to do with Physics nor will I ever talk about it again. If I pass this course, then we have no more physics for the rest of the way.. which is a real good news for me… Whew, what a day! I don’t know what’s ahead for us in this subject matter. All I can say is… GGness! Ouch!
