The mass of an electron is about `(1)/(2000)` times that of proton.

For the following statements, write T for true and F for false : (a) J.J. Thomson proposed that the nucleus of an atom contains only nucleons (b) A neutron is formed by an electron and a proton combining together. Therefore, it is neutral (c) The mass of an electron is about (1)/(2000) times that of a proton (d) A radioactive isotope of iodine is used for making tincture iodine, which is used as a medicine.

The mass of an electron is (1)/(1838) times that of a proton .

An electron and a proton are circulating with same speed in circular paths of equal radius. Which one among the following will happen, if the mass of a proton is about 2,000 times that of an electron?

An electron accelerated under a potential difference of V volt has a certain wavelength lamda It is known that the mass of a proton is about 1800 times the mass of an electron . If a proton has to have the same wavelength lamda , then it will have to be accelerated under the potential difference of

An electron accelerated under a potential difference of V volt has a certain wavelength lamda It is known that the mass of a proton is about 1800 times the mass of an electron . If a proton has to have the same wavelength lamda , then it will have to be accelerated under the potential difference of

Determine the de Broglie wavelength of a proton, whose kinetice energy is equal to the rest of the mass energy of an electron. Given that the mass of an electron is 9xx10^(-31) kg and the mass of a proton is 1837 times as that of the electron.
