Homework Statement A spacecraft is in a circular orbit of radius 3.1 X 10^4 km around a 1.9 X 10^30 kg pulsar. The magnetic field of the pulsar at that radial distance is 1.4 X 10^2 T directed perpendicular to the velocity of the spacecraft . The spacecraft is 0.20 km long with a radius...

I am totally confused. I am not even sure what MeV means.

ok but don't I still have to find the value for v?

would it be Change In P.E.=(q)(potential difference) (1.6X10^-19)(264)= 4.224X10^-17

1/2mvf^2+1/2mvi^2= mghi+mghf

the potential energy?

1/2mvf^2?

Homework Statement A cosmic-ray proton in interstellar space has an energy of 21.5 MeV and executes a circular orbit having a radius equal to that of Earth's orbit around the Sun (1.50 X 10^11 m). What is the magnetic field in that region of space? Homework Equations B=(Mo)(I)/...

so do i need to multiply 1.6X10^-19 by 6.25X10^18 to get the charge(q)?

so what do i do with the 6.25X10^18?

im clueless

So how do I find q?

well i re-did my calculation and every way i work it i still get that same answer. and i am not sure what you mean by calculating the charge on the ion.

(95)(2.5X10^20)=2.375X10^22 (2.375X10^22)(.844)(.259)(sin59)= 4.4X10^21

ok well i multplied the two numbers and got: 2.375X10^22. however once i plugged this into the equation to deteremine the magnetic force i got 4.45X10^21 which is incorrect so I am still unsure where i went wrong?
