two electric charges, eagh of+6.00μ C are placed at thecorners of the base of the square of the side s=8.50m. two othercharges of -6.00μ C are placed at the top of the corners ofthe square.
a) calculate the magnitude of the force on each of the charges?
b) calculate the value of the electric firld at the position ofeach of the 4 charges.
