Two infinite parallel plates 10 mm apart have maintained between them a potential difference of 100 V. The acceleration of an electron placed between them is______________?
Correct answer: D. 1.76 x 10^15 m/s2
- A. 0.56 x 10^15 m/s2
- B. 1.5 x 10^15 m/s2
- C. 1.6 x 10^15 m/s2
- D. 1.76 x 10^15 m/s2
Explanation
The field between the plates is E = V/d = 100/0.01 = 10,000 V/m. Using a = eE/m for an electron gives approximately 1.76 × 10¹⁵ m/s², corresponding to option d.
