MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER Particle A of charge 3.50 x 10"" C is at the origin, particle B of charge -6.05 x 10"" C is at (4.32 m, 0) and particle C of charge 1.50 x 10-" C is at (0, 3.58 m). a) What is the x-component of the electric force exerted by A on C? IN b) What is the y-component of the force exerted by A on C? N (c) Find the magnitude of the force exerted by B on C. N (d) Calculate the x-component of the force exerted by B on C. N e) Calculate the y-component of the force exerted by B on C. N f) Sum the two x-components to obtain the resultant x-component of the electric force acting on C. N 9) Repeat part (f) for the y-component. N (h) Find the magnitude and direction of the resultant electric force acting on C. magnitude N direction counterclockwise from the +x-axis Need Help?

The ends of the molecule become singly ionized: negative on one end, positive on the other. The helical molecule acts like a spring and compresses 1.23% upon becoming charged. Determine the effective spring constant of the molecule. IN/m Need Help? Read It
