CAPE Physics Unit 2 · 2004 · Paper 2 · Question 5(b)(iv)

An electron moving with velocity v perpendicular to a uniform magnetic field B directed out of the page, as shown in Figure 5.

On the Figure 5 copied in your answer booklet, draw the path of the electron if the magnetic field B was reduced to half its value.

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