In Rutherford’s scattering experiment, choose the correct statements are given below.I. Only α-particles are scattered backwards but not protons.II. α-particles cannot be effectively scattered by electrons because α-particles are positively charged.III. Radius nucleus of target is between 9.6 x 10-15 m to 4.8 x 10-15 m.IV. α-particles with energy greater than a certain critical value are not scattered back.(a) Only statement II is correct(b) Only statement III is correct(c) Statements I, III and IV are correct(d) All statements are correct |
