Question

The given image shows alpha rays A, B, C, D striking a gold foil in Rutherford's alpha-ray scattering
experiment. Identify the alpha ray which most likely suggests the presence of a positively charged
nucleus of an atom.
A
B
C
D​

Answer 1

Answer:

B is the answer I hope this is correct

Answer 2

The rays which represent α-ray particles that strike a positively charged nucleus is 'A'.

• α particles are positively charged Helium ions represented as $He_{4}^{2+}$.
• When the positively charged α ray particles strike the nucleus of an atom, it retraces its path.
• If the α particles go through the space of the atom, it goes without deviating in a straight line.
• But if the α particles strike near the nucleus, the particles got deviated from their path from an angle less than or greater than 90° depending upon the distance from the nucleus.
