1.1 Suppose a particle enters with a velocity into a region with a constant magnetic field in the direction perpendicular to the page as shown in Fig. We can state that: a. All particles have the same charge b. The charge of particles 1 and 3 are the same c. The charge of particle 1 is positive d. The charge of particle 3 is negative e. Particle 2 has no charge. B

1.) An electric field points to the right. An electron placed in that field experiences a force towards: A) Right B) Left 1). C) Either Up or Down D) It experiences no force 2.) When you double the distance between 2 electric charges, the force between them: A) Increases by a factor of 2 B) Increases by a factor of 4 C) Decreases by a factor of 2 Decreases by a factor of 4 2)

Consider the arrangement of the point charges shown below. Charge q1 has a value of 6.00 CC and charge q2 has a value of -1.00 CC .  What will be the magnitude and direction of the force on the electron at the bottom if the other charges are held in place? a) The magnitude of the force on the electron will be: b) The electron will experience the force at an angle of: (note the +x-axis is defined as 0 degrees.

H.w : Charges +Q and +30 are separated by a distance 2m. A third Charges is located such that the force on it is Zero (the electrostatic system is in equilibrium). Find the location and the value of the third charge in terms of Q.
