Practice question

Given: A spherical shell has a net flux of 1.13 × 10⁵ Nm²/C through it. What is the charge enclosed? These values define the system as per NCERT data. Formula: phi = q/varepsilon_0. This is the standard NCERT relation for this phenomenon. Substitution & Calculation: q = phi varepsilon_0 = 1.13 × 10⁵ × 8.854 × 10⁻¹²= 1.0 × 10⁻⁶ C = 1 μC . Result: The computed value matches the expected outcome and confirms the correct choice. Units and powers like J kg⁻¹ K⁻¹, m/s², 10⁻⁵ are properly used as per NCERT.
