1. The problem statement, all variables and given/known data The figure shows 11 paths through a region of uniform magnetic field. One path is a straight line; the rest are half-circles. The table gives the masses, charges, and speeds of 11 particles that take these paths through the field in the directions shown. Which path in the figure corresponds to which particle in the table? 2. Relevant equations r = (mv)/(qB) 3. The attempt at a solution I don't know how to use that equation to get the answer but I know particle 11 should be k. What tells how big the semi circle is and where it starts? Please help! Thank you!
