3. Suppose that the four identical particles at the comers of a square all have charge IS \"C and that the square's side length is 4 cm. What are strengths of the x and y components of the force that particle l exerts on particle 4? [Note that the word 'strength' here means magnitude, so all signs should be positive] [Enter the I component in the rst answer box and the 3; component in the second answer box] F: X F, = Submit All Answers 4.
