In a uniform electric field, point A is taken as the reference. The potential difference between points A and B, which are 0.50 m apart along the positive x‑direction, is \(\Delta V_{AB}= -30\ \text{V}\). The potential difference between points A and C, which are 0.40 m apart along a direction that makes \(60^{\circ}\) with the positive x‑axis, is \(\Delta V_{AC}= -20\ \text{V}\). Determine the magnitude of the electric field (in V m\(^{-1}\)) and its direction measured counter‑clockwise from the positive x‑axis.

Answer Options

Correct Answer A. 64 V/m, 21° above the +x axis
B. 48 V/m, 30° above the +x axis
C. 80 V/m, 15° above the +x axis
D. 64 V/m, 45° above the +x axis
Correct Answer
A
Correct Option:
64 V/m, 21° above the +x axis
