1.) Four equal magnitude point charges (3 uC) are placed at the corners of a square that is 4 cm on a side. Two diagonally opposite each other, are positive and the other two are negative. Determine the force on either negative charge.
2.) Charges of +2,+3, and -8 uC are placed at the vertices of an equilateral triangle of side 10 cm. Calculate the magnitude of the force acting on the -8 uC due to the other two charges
