The bottom section acts as a velocity selector, so that the crossed electric field (uniform in the entire region) of strength 2.08X105 V/m and magnetic field allows only positive ions q with a certain velocity to reach the slit S1. After passing through the S1, the singly ionized positive ions experience a magnetic force only (same uniform magnetic field as bottom section), which can separate isotopes with different masses, and only selected mass will reach one of the slits S2 or S3. a. What is the mass of the particles that will reach the second slit, if the distance between the slits are 40 cm (1 and 2 or 1 and 3). b.
