Electric force equals charge times field strength (F = qE)

Steps:

• Use F = qE to find E = F / q.
• Convert charge: q = 2 μC = 2 × 10^{-6} C.
• Substitute values: E = (1.0 × 10^{-2} N) / (2 × 10^{-6} C) = 5.0 × 10^3 V m^{-1} = 5.0 V m^{-1}.
• Direction: Positive charge experiences upward force, so field points upwards.

Why D is correct:

• Matches E = 5.0 V m^{-1} upwards from F = qE, where force direction aligns with field for positive q.

Why the others are wrong:

• A: Wrong magnitude (0.20 instead of 5.0) and direction (downwards).
• B: Wrong magnitude (0.20 instead of 5.0) but correct direction.
• C: Correct magnitude but wrong direction (downwards).

Final answer: D
