Question

calculate the momentum of an electron and associated wavelength when kinetic energy is 150eV
​

Answer 1

Answer:

Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v2. If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
