Three charges `q_1 = 1 xx 10^(-6) C, q^2 = 2 xx 10^(-6)C, and q_3 = -3 xx 10^(-6) C ` have been placed as shown in figure. Then the net electric flux will be maximum for the surface

A

1. `S_1`

B

2. `S_2`

C

3. `S_3`

D

4. same of all three

Text Solution

Verified by Experts

The correct Answer is:
A
a. Charge inside `S_1` = `q_1 +q_2 = 3 xx 10^(-6)C`
Charge inside `S_2` = `q_2 + q_3 = -1 xx 10^(-6)C`
Charge inside `S_3` = 0
Charge inside `S_1` is greatest. So, flux through `S_1` is maximum.
