... and the point at which they leave. The angle at which the protons leave the field with respect to the horizontal is then β = α based on the geometry of the figure above. Once we know r, given d, we can find α by noting sin α = d/r. The radius of the circular path of the protons can be found by notin ...

... q3. Use Coulomb’s law (equation 19-5) and the superposition of forces to find the net electrostatic force (magnitude and direction) on q3 and set it equal to zero. Supposing q3 to be a positive charge, the force from q1 will be repulsive and to the right, and the force from q2 will be attractive and ...

... dt dt example: A 50.0 kg woman walks from one end of 5m, 40.0 kg canoe to the other. Both the canoe and the woman are initially at rest. If the friction between the water and the canoe is negligible, how far does the woman move relative to shore? How far does the boat move relative to shore? ...
