Answer: 1.76×10¹⁴ m/s².
- A 1.76×10¹¹ m/s²
- B 1.76×10¹⁴ m/s²
- C 1.6×10¹⁶ m/s²
- D 9.1×10¹³ m/s²
Correct answer: B. 1.76×10¹⁴ m/s²
Explanation: a = eE/m = 1.6×10⁻¹⁹·1000/9.1×10⁻³¹ ≈ 1.76×10¹⁴ m/s².
Field lines always point from positive to negative charge, are denser where the field is stronger, and never cross; an isolated positive charge has lines radiating symmetrically outward, while a dipole's lines curve from the positive to the negative charge.
