Our teacher supplied us with one 8.5x11 sheet of paper, 2 paper clips and 12in of masking tape. What we have to do is put this stuff together and release it from about 9 feet above the ground. I has to stay in the air for 8 seconds or more and land inside a box on the floor (which means it...
Ok. So i got that part where you replace x with x'cos(theta)+y'sin(theta) and y with -x'sin(theta)+y'cos(theta). My book shows us the proof for this using matrices. What my teacher wants us to do its prove this using polar equations or something like that.
I started out with the drawing...
hmm so r=mv/qB is derived from mv^2/r=qvB. I got r=(1.4x10^-8)v. the thing is.. i dont kno the relationship between the time, radius and velocity. Do i use r to find the circumference and multiply that by the velocity? im not really sure..
thanks for the response
A proton moves in a circular orbit perpendicular to a uniform magnetic field of 0.758T. Find the time it takes the proton to make one pass around the orbit.
Just need someone to help me start off. All I have is that the B=0.758T, q=1.6x10^-19C and m=1.67x10^-27kg. What formulas do I need...
A proton accelerates from rest in a unifor electric field of 640 N/C. At some later time, its speed is 1.20X10^6m/s. Find the magnitude of the acceleration of the proton.
Hmm.. not sure what formula to use on this one.. can someone help?
