Please add description.Five identical charges, `q_1` each, are placed at the vertices of a regular pentagon having side length `l_1`. The net electrostatic force on any of the charges due to other four is `F_1`. Find the electrostatic force `F_2` on any one of the five identical charges, `q_2` each, placed at the vertices of a regular pentagon having side length `l_2`.
