Suppose there are two point charges, one with a positive charge of +30 nC and the other with a negative charge of -20 nC. A distance of 6.0 cm separates these charges. An electron is initially at rest and released from a position equidistant between the charges. Calculate the speed of the electron after it has travelled a distance of 2.0 cm.

• A. 8.0 × 10⁷ m/s
• B. 5.4 × 10¹⁵ m/s
• C. 7.4 × 10¹⁰ m/s
• D. 7.2 × 10¹⁵ m/s
