(1) Both Statement-I and Statement-II are correct.
(2) Both Statement-I and Statement-II are incorrect.
(3) Statement-I is correct and Statement-II is incorrect.
(4) Statement-I is incorrect and Statement-II is correct.
Statement-I: If the De Broglie wavelengths for proton and for \( \alpha \) particles are equal, then ratio of their velocities will be \( 1: 2 \)
Statement-II: De Broglie wavelength \( (\lambda)=\frac{\mathrm{h}}{\mathrm{mv}} \)
