An electron is continuously accelerated in a vacuum tube by applying potential difference. If the de-Broglie's wavelength is decreased by 10%, the change in the kinetic energy of the electron is nearly (B) increased by 23.4% (A) decreased by 11% (D) increased by 11.1% (C) increased by 10% Toll Eree: 1800-120-1021
