A 5.5 kg box is pushed across the lunch table. The acceleration of the box is 4.2 m/s2. What was the net force applied to the box?

Three charges are fixed in place as shown. the squares in the grid have sides of length s = 0.24 m. the magnitude of q is 3 μcoulombs (1 μcoulomb = 10-6 coulombs), while the magnitude of q is 4.5 μcoulombs.

This equation represents Newton's Second Law of Motion, F=ma. It shows the relationship of force, mass, and acceleration.
