CSEC Physics · January 2015 · Paper 2 · Question 6(a)(ii)

To separate emissions from a radioactive source, they are subjected to a uniform electric field, E, perpendicular to their path as shown in Figure 5.

If the electric field is replaced by a uniform magnetic field into the page, predict the path of the emissions.

This question uses a figure or table from the paper — you'll see it when you practise.
