This question is worth 1 point: Two particles with the same positive charge, +q, are moving with identical velocities, v, in two different electric fields (Case 1 and Case 2). These fields have the same magnitude, E, but different directions.
Added by Mike A.
Step 1
Since both particles have the same positive charge, +q, and are moving in electric fields with magnitude E, the force on each particle can be calculated using the formula \( F = qE \). The direction of the force will depend on the direction of the electric field. Show more…

When a positive charge q is placed in the field created by two other charges Q1 and Q2, each a distance r away from q, the acceleration of q is Select one: a. in the direction of the charge Q1 or Q2 of greater magnitude. b. in the direction of the negative charge if Q1 and Q2 are of opposite sign. c. in a direction determined by the vector sum of the electric fields of Q1 and Q2. d. in the direction of the charge Q1 or Q2 of smaller magnitude. e. in the direction of the positive charge if Q1 and Q2 are of opposite sign.

In each case, four charged particles, each with a charge magnitude Q, are fixed on grids. The cases are identical except for the signs of the charges.

Part A: Below, Case A shows a point charge +Q = 0.1C that is held in place on the edge of a circle of radius R = 1m. Case B shows 9 identical point charges of charge +Q/9 (i.e., one-ninth the charge in Case A) placed symmetrically about the horizontal axis on a circle of the same radius R. They too are held in place. CASE A CASE B Calculate the electric field at the center of the circle P for Case A. Remember to specify direction: (3 pts) A student says that the electric potential (V) at the center of the circle in Case B is identical to Case A. Is this student correct or incorrect?
