// Scilab code: Ex3.4 : Momentum of an electron: Pg: 78 (2008)
m = 9.1e-031; // Mass of an electron, kg
E = 1.6e-010; // Kinetic energy of an electron, joule
// Since E = p^2/2*m; // Kinetic energy of an electron, joule
p = sqrt(2*m*E); // Momentum of an electron, kg-m/s
printf("\nThe momentum of an electron = %3.1e kg-m/s", p);
// Result
// The momentum of an electron = 1.7e-020 kg-m/s
