Question

Two point charges: -25µC and +50µC, 10 cm apart. Field at point P, 2 cm from negative charge? (repeat)
Options
A 7.03×10⁸ N/C towards positive
B 4.92×10⁸ N/C towards positive
Correct Answer
C 5.63×10⁸ N/C towards negative
D 6.33×10⁸ N/C towards negative
Correct Answer

Option B is the correct answer.

Detailed Explanation

E1 = k(25e-6)/(0.02)² = 5.625×10⁸ towards positive. E2 = k(50e-6)/(0.08)² = 7.03×10⁷ away from positive. Net = 4.92×10⁸ towards positive.

Hint

E = kq/r², vector sum.
