QvB=mg Right?
solve for B
At a certain location, the horizontal component of the earth's magnetic field is 2.5 x 10^-5 T, due north. A proton moves eastward with just the right speed, so the magnetic force on it balances its weight. Find the speed of the proton.

can you please show me what you are doing to solve for v (not B)
v = QB/mg
For Q, use the charge of a proton, in Coulombs. For m, use its mass. The values for proton mass ansd charge are readily available in your textbook or online.
g= 9.8 m/s^2
