NEET Physics Question (2026) — Solution

Step-by-step solution

In the Geiger-Marsden ( -particle scattering) experiment, the number of -particles scattered at an angle is given by the Rutherford scattering formula: N( ) 1 ^4( /2) From this relation, we can observe the following: 1. For small values of , ( /2) is very small, making N( ) very large. Most -particles pass through with very little deflection. 2. As the scattering angle increases, ( /2) increases, causing the number of scattered particles N( ) to decrease rapidly. 3. The minimum number of scattered particles occurs at = 180^ , where (180^ /2) = (90^ ) = 1. The graph that correctly represents this rapid decrease from a very high value at small angles to a low value at large angles is shown in option (4). Answer:
