yeah that fourth row subtraction may have been the best... oh well i solved it by converting that into 4 3x3 matrices and then solving all of those 3x3 matrices. thanks for the replies though.

Homework Statement Hello, I am stuck on this particular question for my homework. It is a 4x4 Matrix that consists of a b b b b a b b b b a b b b b b The Attempt at a Solution My approach has been to factor out the a to give the first row of 1 b b b and then use...

No it was asking for metres which is what my answer is in.

I got 8.698*10^(-3) for my radius. The computer kept telling me it was incorrect but I managed to get the right answer with this value so I do not know what is wrong...

Thanks for trying to help.

Well the question involved some steps and one of the steps was to find the radius. It continued to tell me I am wrong. I decided to stop using that and work on it my own using my method and I managed to come up with the correct answer, which just involved me to not round to 2 sig figs but add on...

Oh sorry, I edited the post. It is coming out of the screen. So it is perpendicular to its motion which means it will create a net force on the proton and cause it to undergo the circular motion.

Homework Statement A proton (mass= 1.67×10-27 kg, charge= 1.6×10-19 C) traveling with speed 1×106 m/s enters a region of space containing a uniform magnetic field of 1.2 T. The magnetic field is coming out of the screen. What is the time t required for the proton to re-emerge into the...
