The mass of a proton is about 2,000 times the mass of an electron. An electron and a proton are injected into a uniform electric field at right agles to the direction of the field with the same initial kinetic energy. Then

Assertion : If an electron and proton enter an electric field with equal energy, then the path of electron is more curved than that of proton. Reason: Electron has a tendency to form curve. (A). If both assertion and reason are true and reason is the correct explanation of the assertion, (B) if both assertion and reason are true but reason is not correct explanation of the assertion. (C) if asssertion is true, but reason if false, (D) if both assertion and reason are false

Determine the de-Broglie wavelength of a proton, whose kinetic energy is equal to the rest mass energy of an electron. Given that the mass of an electron is 9.1 xx 10^(-31) kg and the mass of a proton is 1,837 times as that of the electron.

Calculate the De-Brogile wavelength of an electron and proton if their 10^5 m//s given mass of electron is 9.1 xx 10^(-31) kg (kilogram). Mass of proton 1.67 xx 10^(-27) kg . Plank.s constant h=6.625 xx 10^(-34) JS (Joule Second).

True of False : The number of unpaired electrons in V^(2+) is 2

(true/false) A neutron is formed by an electron and a proton combining together. Therefore, it is neutral

Calculate the de-Bronglie waveelngth for electron and protonif their speed is 10^5 m s^(-1) .Given,mass of an electron =9.1 xx 10^(-31) kg ,mass of proton = 1.67 xx 10^(-27) kg and Planck's constant = 6.62 xx 10^(-34) J s .
