For any fixed distance, the electromagnetic force between two protons is \(10^n\) times of the gravitational force between them. Then \(\mathrm{n}=\)
- A \(26\)
- B \(13\)
- C \(39\)
- D \(36\)
Answer & Solution
Correct Answer
(D) \(36\)
Step-by-step Solution
Detailed explanation
\( \frac{F_e}{F_g} = \frac{k_e e^2}{G m_p^2} \) \( \frac{F_e}{F_g} = \frac{(9 \times 10^9 \, \text{N m}^2/\text{C}^2) (1.6 \times 10^{-19} \, \text{C})^2}{(6.67 \times 10^{-11} \, \text{N m}^2/\text{kg}^2) (1.67 \times 10^{-27} \, \text{kg})^2} \)…
