Answer 1

Answer #1

Here centripetal force is balanced by magnetic force

qvB = mv²/r

=>r=mv/qB =(1.67*10^-27)(3*10⁸/2)/(1.6*10^-19)(50*10^-6)

r =3.1363*10⁴ m

A cosmic ray proton moves at an initial velocity of 0.8 the speed of light from directly overhead earth towards the equator, entering the earth's magnetic field at a distance of 500 km. Assuming the earth's magnetic field is parallel to the earth's surface, calculate if the proton will hit the earth's surface. Use Rearth = 6.37 x 103 km. Draw a diagram to illustrate the calculations.
