IB Physics Electric and Magnetic Fields

/

Tutorial questions on problems with electric and magnetic fields present are given below.

  1. Two charged particles moving to the right at the same speed enter a uniform electric field. Both particles curve upwards in identical paths. Both particles must have the same (a) mass, (b) charge, (c) charge to mass ratio, (d) initial momentum
  2. Did J. J. Thomson use the method of "balancing" the electric and magnetic forces on a beam of cathode rays in his original experiment?

IB Physics Wheatstone Bridge

/

Below is a tutorial sheet on resistor combinations.

  1. Five identical resistors form a bridge configuration. A current I enters the group. Find the current in the bridge resistor.

  2. Resistances of 2Ω, 3Ω, 4Ω and 5Ω are placed clockwise around the sides of a square loop (in order from top left). Find the value of the vertical bridge resistor if no current flows through it when the configuration is connected to a 12 V battery.
