An electron of mass (m) having de-Broglie wavelength ‘λe’ and a proton of mass (m) having de-Broglie wavelength ‘λp’ are accelerated through the same potential difference. The ratio of ‘λe’ to ‘λp’ is: [MHT-CET 2023]

The magnetic moment produced in a substance of 10^-3 kg is 5 × 10^−7A−m2. If its density is 6 X 10^3 kg/m^3, then the intensity of magnetisation in A/m will be :

In a photoelectric emission experiment, the stopping potential for a given metal is ‘V’ volt, when radiation of wavelength ‘λ’ is used. If radiation of wavelength ‘2λ,’ is used with the same metal, then the stopping potential (in volt) will be: [c = velocity of light, e = charge on electron, h = Planck’s constant] [MHT-CET 2023]
