Hey all, I have a unit test tomorrow on Gravitational and Electric Fields. If you have any good practice questions for Grade 12 University level please leave them below! :) In my class we've learned gravitational force, gravitational field strength and orbits (omit geosynchronous) as well as Coulomb's law and electric-static force and electric field strength. I am looking for difficult questions in 1D and 2D! Thank You!
