Final answer:
To reduce the cross section for inelastic e-p scattering to the Rosenbluth's formula, you need to choose the appropriate values for the electromagnetic and magnetic structure functions.
Step-by-step explanation:
To reduce the cross section for inelastic e-p scattering to the Rosenbluth's formula for elastic e-p scattering, you need to choose the appropriate values for the electromagnetic structure function (W2) and the magnetic structure function (W1).
The Rosenbluth's formula includes the electric and magnetic form factors (GE and GM) that describe the interaction between the electron and the proton.
By choosing the appropriate values for W1 and W2, you can derive the Rosenbluth's formula from the inelastic cross section equation.
