(a(i))[2]
Enter the symbol $\alpha$ once in Table 8.1 to show any deflection of the $\alpha$-particles. Enter the symbol $\gamma$ once in Table 8.1 to show any deflection of the $\gamma$-rays.
(a(ii))[2]
Enter the symbol $\alpha$ once in Table 8.2 to show any deflection of the $\alpha$-particles. Enter the symbol $\gamma$ once in Table 8.2 to show any deflection of the $\gamma$-rays.
(b(i))[3]
State and explain the direction in which the coil rotates as viewed from point X.
(b(ii))[1]
State what the moment is in this position.
(b(iii))[2]
By considering the forces on the coil, explain how the split-ring commutator allows the motor to keep turning continuously.
