(i) Explain whether the algebraic sign of a particle’s charge affects the magnitude of its de Broglie wavelength when it is accelerated through a given magnitude of potential difference.
(ii) Support your explanation with suitable mathematical reasoning.
(iii) An electron and a positron (same mass as electron but charge +e) are each accelerated from rest through 500V. Compare the magnitudes of their de Broglie wavelengths.
