Answer 1

Explanation:

Given The four small spheres shown in figures carry charges q1 = 4 nc - 7.8 nC, q3 = 2.4 nC and q4= 1 6 nC Calculate the flux passing through each of the three closed surfaces S1, S2, and S3   in figures.​

• First we need to find flux.
• So flux φ =closed  ∫E.ds
•                = q enclosed / εo
• So flux of s1 will be  
• So φ (s1) = q1 / εo  (1/4πεo = 9 x 10^9
•                                  Or 1 / εo = 9 x 4π x 10^9 )
•               = 4 x 10^-9 x 9 x 4π x 10^9
•              = 16 π x 9
•              = 452.16 Nm^2 / C
• Similarly for flux of s2 will be
• So φ(S2) = q2 / εo
•               = - 7.8 x 10^-9 x 9 x 4π x 10^9
•              = - 7.8 x 9 x 4π
• = 881.71 Nm^2 / C
• Similarly for flux of s3 will be
• So φ(s3) = q1 + q2 / εo
•               = (4 – 7.8 ) 10^-9 x 9 x 4π x 10^9
•               = - 3.8 x 9 x 4π  
•              = - 429.55 Nm^2 / C

Therefore flux passing through three closed surfaces will be 452.16 Nm^2/C, 881.71 Nm^2/ C, 429.55 Nm^2 / C
