Two charges Q1=+6mC and Q2=+4mC are separated horizontally on a straight line, Q1 being on the left hand side and subsequently Q2 on the right by a distance of 360cm.
a) Determine the magnitude of the electric force between these charges.
b) Determine the amount of work that must be done to move charge Q2, 60cm toward charge Q1 that is 60 cm towards the left hand direction,thus the final direction between Q1 and Q2 will be 300 cm. You may assume that the charges are moved very slowly so that there is no change in the kinetic energy of the charges.
