Consider three point charges, q1, = 4.50 C, q2=4.50 C, and q3 = 6.30 C, located at the corners of an isosceles triangle. The charges q1, and q2 are 5.00 m apart and form the base. The triangle is 3.50 m high, and q3 is located at the top. Calculate the magnitude and direction of the resultant force on q3
