Which of the following statement(s) is true

Options

A. The Kinetic energy of an electron is inversely proportional to square of its momentum
B. de-Broglie wavelength associated with a particle is directly proportional to its mass
C. de-Broglie wavelength associated with a particle is directly proportional to square of its velocity
D. The kinetic energy of an electron is directly proportional to accelerating potential

Answer

D

Explanation

`1//2mv^(2)=K.E.=eV`,
where V is accelerating potential and v is speed of electron.
