Questions and Answers

What is the relationship between the radius of a nucleus (R) and its mass number (A)?

R = R0 * A

$R = R0 \times A^{2}$

R = R0 / A

$R = R0 \times A^{1/3}$ (correct)

What is the relationship between atomic mass number (A) and atomic number (Z)?

$A = Z + N$ (correct)

$A = Z^{2}$

$A = 2Z$

$A = Z \times N$

What is the impact parameter (b) for α-particles directed towards the center of the nucleus?

Coulomb's constant

cot(θ/2)

0 (correct)
