A Thin, Circular Disk of Radius 30

question 8

Multiple Choice

A thin, circular disk of radius 30.0 cm is oriented in the yz-plane with its center at the origin. The disk carries a total charge of +3.00 μC distributed uniformly over its surface. Calculate the magnitude of the electric field due to the disk at the point x = 15.0 cm along the x-axis. (ε0 = 8.85 × 10^-12 C²/N ∙ m²)

• A) 9.95 × 10⁵ N/C
• B) 4.98 × 10⁵ N/C
• C) 3.31 × 10⁵ N/C
• D) 2.49 × 10⁵ N/C
• E) 1.99 × 10⁵ N/C
