$\alpha$-Particles pass through the gold foil deflected by small angles and with reduced speed.

Vedclass · Answer

(A) In the Thomson model,the positive charge is assumed to be uniformly distributed throughout the atom. Since the positive charge is not concentrated in a small central nucleus,the electrostatic repulsion experienced by the $\alpha$-particles would be very weak. Consequently,the $\alpha$-particles would pass through the gold foil with only very small deflections and a slight decrease in speed due to the uniform distribution of positive charge.

If the Thomson model of the atom was correct,then the result of Rutherford's gold foil experiment would have been:
