During a practical session, student A designed a circle of area 9m2 and constructed two perpendicular diameter AB and CD on it. Student B placed four identical charges of +1nC at each end of these diameters. How much energy does Student C need to successfully carry out a charge of +5nC from a distant point to the center of the circle?
