Question

47. The conclusion of Rutherford's scattering experiment does not include

a) The radius of nucleus is less than 10-

14

m.

b) The positively charged particles of

atom move with very high velocity

c) Scattering follows coulomb's law, i.e.,

same charges repel each other

d) α-particles can come within the

distance of order of 10-14

m of the

nucleus

​

Answer 1

Answer:

Option b

Explanation:

+ve charged particles of the atom, i.e. the nucleus, do not move around with high velocities and can be even considered stationary

Answer 2

ANSWER:-

The correct option is The radius of nucleus is less than 10-14m.

EXPLANATION :-

The following were the experiments of Rutherford's scattering experiment:-

• Most of the ray passes through gold foil without deflection , this suggest that most of the space in the atom is empty.
• A very few of them passes from small angle of deviation ,  it is due to repulsive force . The atom has center has positive charge which repels the positive charged alpha particles .
• 1 in 20000 ray bounce back in same path . this suggest there there must be a positive charged due to which the positive charge alpha particles reflect back in same path . This leads to discovery of nucleus.
• positively charged particles have high velocity .
