Question

if magnitude of electric flux entering the closed surface is 5Nm'2/c and leaving the surface is 3Nm'2/c then the magnitude of net electric charge inside is? ​

Answer 1

Dear Nawab,

◆ Answer -

q = 1.77×10^-11 C

◆ Explanation -

◆ Explanation -

# Given -

Φ1 = 5 Nm^2/C

Φ2 = 3 Nm^2/C

# Solution -

Total electric flux through closed surface is -

Φ = Φ1 - Φ2

Φ = 5 - 3

Φ = 2 Nm^2/C

According to Guass's theorem -

Φ = q / ε0

q = Φ × ε0

q = 2 × 8.85×10^-12

q = 1.77×10^-11 C

Therefore, net electric charge inside the enclosed surface is 1.77×10^-11 C.
