Q17. A free particle described by a plane wave and moving in the positive z -direction undergoes scattering by a potential if rsR V(r)=. 0, if r>R If V, is changed to 2V,, keeping R fixed, then the differential scattering cross-section, in the Born approximation. (a) increases to four times the original value (b) increases to twice the original value (c) decreases to half the original value
