Mathematical expression of Graham’ s law is …… (a) rA / rB = MB / MA (b) rA / rB = √(MA / MB) (c) rA / rB = √(MB / MA)

Question

Mathematical expression of Graham’ s law is ……

\((a) \frac{r_A}{r_B}=\frac{M_B}{M_A}\)

\((b) \frac{r_A}{r_B}=\sqrt\frac{M_A}{M_B}\)

\((c) \frac{r_A}{r_B}=\sqrt\frac{M_B}{M_A}\)

\((d) \sqrt\frac{r_A}{r_B}=M_A.M_B\)

Answer 1

\((c) \frac{r_A}{r_B}=\sqrt\frac{M_B}{M_A}\)
