An electron is moving with a kinetic energy of `2.2275 xx 10^(-25)J`. Calculate its de-broglie wavelength.

If the velocity of the electron in Bohr's first orbit is 2. 19 xx 10 ^(5) ms ^(-1). Calculate the de-Broglie wavelength associated with it .

Calculate the de-Brogile wavelength of an electron.

The mass of an electron is 9.1 xx 10 ^(-31) kg . If its K. E. is 3. 0 xx 10 ^(-25) J, calculate its wavelength.

An electron travels with a velocity of x ms^(-1). For a proton to have the same de-Broglie wavelength, the velocity will be approximately:

For what kinetic energy of a neutron will the associated de-Broglie wavelength be 1.40 xx 10^-10m ?
