Scientists say that it is hard to track how monarch butterflies migrate
Answer:
a)
is the speed of each proton
b) 
Explanation:
Given:
radius of path of motion, 
we know charge on protons, 
magnetic field strength, 
we've mass of proton, 
a)
From the equivalence of magnetic force and the centripetal force on the proton:



where:
v = speed of the proton

is the speed of each proton
b)
Now the centripetal force on each proton:
