**Problem Description:**

A uniformly charged conducting sphere of 1.3 m diameter has a surface charge density of 9.4 μC/m². 

**Questions:**

(a) Find the net charge on the sphere.

(b) What is the total electric flux leaving the surface of the sphere?

**Solution Inputs:**

(a) 
  - Number: [Input box] 
  - Units: [Dropdown menu]

(b) 
  - Number: [Input box]
  - Units: [Dropdown menu]

**Steps to Solve the Problem:**

1. **Calculate the Net Charge on the Sphere:**

   Given:
   - Diameter of the sphere, \(d = 1.3 \, \text{m}\)
   - Surface charge density, \(\sigma = 9.4 \, \mu\text{C/m}^2\)

   - Radius of the sphere, \(r = \frac{d}{2} = \frac{1.3 \, \text{m}}{2}\)

   Use the formula for the surface area of a sphere, \(A = 4 \pi r^2\), to find the surface area.

   Net charge \(Q\) is calculated using \(Q = \sigma \times A\).

2. **Calculate the Total Electric Flux:**

   According to Gauss's law, the total electric flux \(\Phi\) leaving a closed surface is related to the net charge \(Q\) by:

   \(\Phi = \frac{Q}{\epsilon_0}\),

   where,
   - \(\epsilon_0\) is the permittivity of free space (\(8.85 \times 10^{-12} \, \text{C}^2/\text{Nm}^2\)).
