electric flux is independent of radius but dependent on charge enclosed and equal to 1/ε times the charge enclosed
hence electric flux= 7.6×10⁻⁶/8.85×10⁻¹²
hence electric flux= 7.6×10⁻⁶/8.85×10⁻¹²

Answer:
The electric flux through the center of the sphere is 8.58×10⁵Nm²C⁻¹.
Explanation:
The electric flux through the center of the sphere is given as,
(1)
Where,
Ф=flux through the center of the sphere
q=charge placed at the center of the sphere
∈₀=permittivity of free space=8.8542×10⁻¹²C²N⁻¹m⁻²
From the question we have,
Charge placed at the center of the sphere(q)=7.6μC=7.6×10⁻⁶C
By placing the value of the charge and permittivity in equation (1) we get;
Hence, the electric flux through the center of the sphere is 8.58×10⁵Nm²C⁻¹.
