Question

Consider the situation shown in the figure. What are the signs of q1 and q2? If the lines are drawn in proportion to the charges, what is the ratio q1/q2?
Figure

Answer 1

(The diagram missing in the question is attached below)

Given :

Number of lines passing through q₁ = 3

Number of lines passing through q₂ = 3

To Find :

The signs of q₁ and q₂

The value of the ratio q₁/q₂

Solution :

• The electric field lines of force are entering the charge q₁, so the sign of the charge q₁ is negative.

• The electric field lines of force are leaving the charge q₂ , so the sign of the charge q₁ is positive.

• As the lines are drawn proportional to the charges

                    $\frac{q_{1} }{q_{2} } = \frac{6}{18} =\frac{1}{3}$

The sign of q₁ is negative and the sign of q₂ is positive

The value of the ratio  q₁/q₂ is 1:3

Answer 2

Answer:

q1 is negative

q2 is positive
