What is the number of significant figures in each of the following ? (i) Mass of electron = 9.108 xx 10^(-31) kg (ii) Mass of proton = 1.672 xx 10^(-27) kg (iii) 0.00564 .

Calculate the equivalent energy of electrons and proton at rest. Given that mass of electron =9.1xx10^(-31)kg and mass of proton =1.673xx10^(-27)kg .

How many electrons (mass 9.1xx10^-31 kg) would balance one Proton (mass 1.67xx10^-27 kg)

Considering the wavelengths of electron and proton to be equal,the ratio of their velocities (v_(e)/(v_(p) would be: (mass of electron =9.1times10^(-31)kg, mass of proton =1.67 times10^(-27)kg

When would the wavlength associated with an electron became equal to that with proton? (Mass of electron =9.1095xx10^(-31)kg," Mass of proton "=1.6725xx10^(-27)kg)

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).

When would the wavelength associated with an electron become equal to that with proton ? (Mass of electron = 9.10 xx 10^(-31) kg , Mass of proton =1.6725 xx 10^(-27)kg )

When would the wavelength associated with an electron become equal to that with proton ? (Mass of electron = 9.10 xx 10^(-31) kg , Mass of proton =1.6725 xx 10^(-27)kg )
