They are asking for a complete writeup of the solution in the form of a statement, assumptions, method, analysis and conclusions. I do not have tiome to do that for you.

The velocity selector has the B field perpendicular to the page, with v*B = E. The Electric force balances the magnetic force. The E field goes from positive to negative plate. Use the right hand rule to get the B direction there.

In the detection chamber,

m v^2/r = B v e, with a different value of B, but the same v as above. Use that to solve for the mass M
