uncertainty principle
an electron inside spherical metallic particle of volume 10^ -12 metre cube has a kinetic energy about 10 eV. use uncertainty relations to find relative uncertainty in electron velocity .

physics
Q1) consider a stationary nucleus of mass M. show that the minimum energy the photon must have to create an electron-positron pair in the presence of stationary nucleus is 2mc^2(1+ m/M) where m is the rest mass of the electron.
