A filament running along the x axis from the origin to x = 80.0 cm carries electric charge with uniform density. At the point P with coordinates (x = 80.0 cm, y = 80.0 cm), this filament creates electric potential 100 V. Now we add another filament along the y axis, running from the origin to y = 80.0 cm, carrying the same amount of charge with the same uniform density. At the same point P, the
pair of filaments creates potential: 1.greater than 200 V. 2.200 V. 3.100 V. 4.between 0 and 200 V. 5.0.
