1. The problem statement, all variables and given/known data A point charge q1 = 4.40 μC is at the origin and a point charge q2 = 6.00 μC is on the x axis at x = 2.49 m. i) Find the electric force on charge q2 ii) Find the electric force on charge q1 2. Relevant equations Coulomb's law F = k (q1q2)/d^2 3. The attempt at a solution Part i) Using k = 8.99 x 10^9, q1 = 4.40 x 10^-6, q2 = 6.00 x 10^-6 and d = 2.49m Plug these values into the equation F = (8.99 x10^9) x (4.40 x 10^-6) x (6.00 x 10^-6)/ (2.49)^2 F = 3.83 x 10^-2 N Checked this value a couple of times and seems correct. Part ii) Since we are looking for the force from q2 to q1, it is the same magnitude but opposite in direction. F = -3.83 x 10^-2 N I'm a little unsure of this, but if feels correct. If I'm wrong, any guidance welcome.
