Two surfaces A and B are enclosing the charges as shown below. The total normal electric induction (T.N.E.I) through the surfaces A and B are respectively.

Options

  1. A+2 q and +2 q
  2. B+q and +3 q
  3. C+q and +2 q
  4. D+2 q and +3 q

Correct answer

C. +q and +2 q

Step-by-step solution

Total normal electric induction is given by, array ll & T.N.E.I. = q_ enclosed & T.N.E.I. for A=(+2 q-q)=+q & T.N.E.I. for B=(+3 q-q)=+2 q array
