Two point charges are located in the XY plane as follows: a charge 2.0x10- C is at the point ( x =0, y =4 cm), and a charge -3.0x10- C is at the point (x = 3, y = 4cm ). (a) If a third charge of 4.0x10-: C is placed at the origin, find the x-component and y- component of the total force on this third charge. (b) Find the magnitude and direction of the resultant force on the charge at the origin also
