NEET Physics Electric Force MCQ Question
Type: MCQ-numerical-Hard
The acceleration for electron and proton due to electrical force of their mutual attraction when they are 1 Å apart is
A
3 × 10¹⁸ m/s², 3.2 × 10¹⁶ m/s²
B
5 × 10²² m/s², 1.4 × 10¹⁹ m/s²
C
1 × 10²² m/s², 1.3 × 10¹⁹ m/s²
D
5 × 10¹⁸ m/s², 1.3 × 10¹⁶ m/s²
Correct Answer
Option C
Detailed Explanation
The acceleration is calculated using Coulomb's law and Newton's second law. The force is given by F = k * e² / r², and acceleration a = F/m.
