Explanation / Answer

Object A, which has been charged to +12 nC, is at the origin. Object B, which has been charged to -26 nC , is at (x,y) = (0 cm, 2 cm). What is the magnitude of the electric force on object A? Distance between the charges =2cm Now force on A=9*10^9*10^-18*12*26/4*10^-4 Newton calculating we will get the answer What is the magnitude of the electric force on object B? Magnitude of the force will be same as experienced by A What is the direction of the electric force on object A it will be in the first quadrant so options A and B are correct What is the direction of the electric force on object B it will be in the third quadrant so options C and D are correct
