Coulomb's law for electrostatic force between two point charges and Newton's law for gravitational force between two stationary point masses, both have inverse square dependence on the distance between the charges`//`masses (a) compare the strength of these forces by determining the ratio of their magnitudes (i) for an electron and as proton (ii) for two protons (b) estimate the accelerations for election and proton due to electrical force of their mutal attraction when they are 1 A apart.

Explanation

To solve the problem step by step, we will break it down into two parts as specified in the question.

### Part (a): Compare the strength of the forces

#### (i) For an electron and a proton

1. **Identify the charges and masses**:
- Charge of an electron, \( q_e = -1.6 \times 10^{-19} \) C
