Electric Charges And Fields

Question

Two charges of magnitudes – 2Q and + Q are located at points (a, 0) and (4a, 0) respectively. What is the electric flux due to these charges through a sphere of radius ‘3a’ with its centre at the origin?

Solution

Using gauss law, we have

$phi space equals space q over epsilon subscript o$

Electric flux is given by,
$straight ϕ space equals space fraction numerator negative 2 straight Q over denominator straight epsilon subscript straight o end fraction$
