O 4 69x106 N/C O 2 96x106 N/C O 6 04x106 N/C O 4.31x106 N/CThere are two point charges q1=(7.000x10^0) µC and q2=(-3.0000x10^0) µC. q1 is located at origin (0, 0). q2 is located at (4.00x10^0) m,(5.000x10^0) m). Now we place another point charge q3 = (1.0000x10^1) µC at ((4.00x10^0) m, 0), i.e. q3 is right underneath of q2. Please calculated the X-component of the electrostatic force on q3 . Give your answer in the unit of N with 3 sf. Note: Use the sign to represent the direction, for example -2.11x10^-4 means the force is on the negative x direction.
