Physics Aviary: Practice Problems: Force Electric Between Two Particles

Students must find the net force on one of the charges in a rectangular arrangement of charges.

Students must find the net force on one of the charges in a line of charges.

Students must find the net force on one of the charges in a triangular arrangement of charges.

Determine the mass and speed of a particle being fired through variable magnetic and electric fields. This problem is done after students determine the charge of an electron using the Millikan Oil Drop Experiment.

Students must find the value of the spring constant based on a graph of force vs. length.

Students must find out the force needed to hold an object stationary on an incline when there is no friction present on the incline.

Students must find out different things for an object in a elevator simply based on the force-time graph that is produced as the object rides in the elevator.

Students must find out the strength of the gravitational force between two spherical objects based on the size, density and distance between centers.

Students must figure out the number of people that can go on a raft without having the raft go fully under the fluid.

Students must calculate the number of rotations per hour required to create a certain force normal on a spinning space station.
