Which of the following statement is incorrect ?

Options

A. Two charged particles having the same mass and accelerasted through same potential difference from rest will have always same value of de-Broglie wavelength.
B. Heisenberg's uncertainty principle is more significant for microscopic particles than for macroscopic particles.
C. The value of wavelength of photons emitted, when an electron in a `H` like sepcies makes transition from a higher orbit, can be calculated both by using `lambda = (hc)/(Delta E)` and by Rydberg's formula, where `Delta E` is difference in energy of two orbits.
D. The radius of the nucles of an atom is directly proportional to the cube root to mass number of that atom.

Answer

A

Explanation

Which of the following ……………
(1) Changes of the two particles may be different, so the de-Broglie wavelength may be different.
