Consider the situation shown in (figure) what are the signs of `q_1` and `q_2` ? If the lines are drawn in proportion to the charge, what is the ratio `q_1/q_2` ?

consider the situation shown in the figure the ratio q_2/q_1 is

In the adjoining figure, the electric field lines for charges q_1 and q_2 are shown. Identify the sign of the charges.

Identify the correct statement about the charges q_1 and q_2 then

In the shown figure shown a. Find q_1 and q_6 b. total electrostatic potential energy .

In the above question, the ratio of masses of the charge particles q_1,q_2, and q_3 is

Two point charges q_1 and q_2 are placed in an external uniform electric field as shown in figure. The potential at the location of q_1 and q_2 are V_1 and V_2 , i.e., V_1 and V_2 are potentials at location of q_1 and q_2 due to external unspecified charges only. Then electric potential energy for this configuration of two charged particle is
