A radioactive source emits only B-particles. (a). A scientist wishes to investigate the deflection of B-particles by an electric field.

Draw a
labelled diagram to suggest a suitable experimental arrangement.[3]

(b) State how the apparatus would be used to show the deflection of the B-particles by the
electric field.

Look at the potential energy diagram for a chemical reaction. which statement correctly describes the energy changes that occur in the forward reaction?
