Question

In the Geiger-Marsden scattering experiment the number of scattered particles detected are maximum and minimum at the scattering angles respectively at

• A. $0^{\circ }$ and $180^{\circ }$
• B. $180^{\circ }$ and $0^{\circ }$
• C. $90^{\circ }$ and $180^{\circ }$
• D. $45^{\circ }$ and $90^{\circ }$

Answer 1

Answer: (A)

The number of scattered particles detected will be maximum at the angle of scattering $\theta =0^{\circ }$ and minimum at $\theta =180^{\circ }$.
