Question

Draw electric field lines for a system of two charges q1 and q2 such that (i) q1q2 > 0; q1 > q2 > 0 (i) q1 q2 < 0; q1 >|-q2| <0, |q1|>|-q2|

Answer 1

Given that,

Two charges q₁ and q₂.

We know that,

If the charge is positive then the electric field line coming out of the charge.

If the charge is negative then the electric field line going into the charge.

We need to draw the electric field line for given condition,

For first case,

(a). $q_{1}q_{2}>0$

(b). $q_{1}>q_{2}>0$

Here, both charges are greater than zero.

For second case

(a). $q_{1}q_{2}<0$

Here, both charges are less than zero.

(b). $q_{1}>|-q_{2}|<0$

(c). $|q_{1}|>|-q_{2}|$

Hence, This is required solution.
