CIE iGCSE Co-Ordinated Science P5.2.2 The three types of nuclear emission Exam Style Questions Paper 2
Question
A radioactive source emits beta (β)-particles and gamma ( $\gamma$)-rays.
Both types of radiation enter the magnetic field between the poles of a magnet, as shown.
In which direction does each type of radiation travel after entering the magnetic field?
▶️Answer/Explanation
Ans : D
Question
A beam of different types of ionising radiation passes through an electric field between two metal plates. The diagram shows the direction of each type of radiation as it passes through the field.

(B) alpha (α)-particles and beta (β)-particles only
(C) alpha (α)-particles and gamma (γ)-rays only
(D) beta (β)-particles and gamma (γ)-rays only
▶️Answer/Explanation
Ans: C
Question
Three types of ionising radiation enter a magnetic field at right angles to the field.
Which types of radiation are deflected?
(A) $\alpha$ and β only
(B) $\alpha$ and $\gamma$ only
(C) β and $\gamma$ only
(D) $\alpha$, β and $\gamma$
▶️Answer/Explanation
Ans: A
Question
Electric and magnetic fields can cause deflection of ionising radiation.
Which statements about the deflection are correct?
1 In an electric field, $\alpha$-particles and β-particles are deflected in opposite directions.
2 In a magnetic field, $\alpha$-particles and β-particles are deflected in the same direction.
3 $\gamma$-rays are not deflected by electric fields or by magnetic fields.
(A) 1 and 3
(B) 1 only
(C) 2 and 3
(D) 2 only
▶️Answer/Explanation
Ans: A
