d. decrease in kinetic energy

Answer 1

CORRECT ANSWER✓✓✓





Due to force of repulsion

Answer 2

Dear Student,

◆ Answer - (b)

In the scattering experiment the deflection of alpha particle is due to force of repulsion.

◆ Rutherford's gold foil experiment -

• In 1911, Rutherford coined the planetary model of atom with the help of his gold-foil experiment.
• In this model, he bombarded alpha particles from radioactive elements on the shining screen.
• He compared the results to atomic structure demonstrating that atom has heavily charged nucleus surrounded by empty space.

Thanks dear. Hope this helps you...
