Archanaasks :Three charges 1 mC, 1 mC and 2 mC are kept at the vertices A, B and C of an equilateral triangle ABC of 10 cm side, respectively. The resultant force on the charge at C is
Archanaasks :3 point charges 1C, 2C & 3C placed at the coners of equilateral triangle of side 1m. The work done in bringing these charges to the vertices of a smaller similar triangle of side 0.5m
