STANDARD Physics Coulomb's Law MCQ Question
Type: MCQ-numerical-Medium
The acceleration for electron and proton due to electrical force of their mutual attraction when they are 1Å apart is
A
3.1 × 10²² m s⁻², 1.3 × 10¹⁹ m s⁻²
B
3.3 × 10¹⁸ m s⁻², 3.2 × 10¹⁶ m s⁻²
C
2.5 × 10²² m s⁻², 1.4 × 10¹⁹ m s⁻²
D
3.5 × 10¹⁸ m s⁻², 1.3 × 10¹⁶ m s⁻²
Correct Answer
Option C
Detailed Explanation
The force of mutual attraction between an electron and a proton is calculated using Coulomb's law. The acceleration is then determined by dividing the force by the mass of the electron and proton respectively. The calculations show that the acceleration values are 2.5 × 10²² m s⁻² for the electron and 1.4 × 10¹⁹ m s⁻² for the proton.
