Assuming the information of the Screenshot (707). Can you solved the problem? (Screenshot (708))

In this section you will estimate particle drift velocities for a proton near the geomagnetic equator. Use the following assumptions:
proton kinetic energy (KE) = 1 MeV; pitch angle a = 90°; altitude z = 3 Rearthi
B(r) = Bo x (Rearth /r); where Bo = 0.3 Gauss and r= z+ Rearth
g(r) = g. × (Rearth /r)2; where go = 9.81 m/s²

The magnitude of the gradient and curvature drift equations can be combined and simplified to an approximate form of
Vdrift = 3 r2 KE / [q B, RE³]
Where KE is the particle's kinetic energy in Joules and the other terms are the same as described above. Using the same values as the previous problem, calculate the
combined drift velocity in m/s for this proton near the equator. Report your answer in scientific notation to 2 significant digits.
