PHY 102 Last Minute Prep Objective Question

A circular ring 5cm in radius has a positive charge of 3×10⁻⁷ C. Compute the electric field intensity on the axis 4cm from its centre.

A 2.60×10⁻¹⁰ N/C

B 4.65×10⁵ N/C

C 3.00×10⁻⁷ N/C

D 4.1×10⁵ N/C

Correct Answer

Option D is the correct answer.

Using the axial field formula: E = kQx/(R²+x²)^(3/2). With R=0.05m and x=0.04m, E = 4.1×10⁵ N/C

Apply the specific formula for the electric field on the axis of a charged ring.
