K = 9 x 10^9 Physics 221 Homework 1 Due January 31
A charge q1 = +5.00 nC (nanoCoulomb = 10^-9 Coulomb) is placed at the origin. A charge q2 = -2.00 nC is placed at x = 4.00 cm and y = 0. A third charge q3 = -6.00 nC is placed at x = 4.00 cm and y = 3.00 cm. What is the x and y components of the total electric force on charge q3? What is the magnitude of the total electric force on q3? What is the direction of the total force on q3?
F = kq1q2 / r^2
