Below are sample questions representative of the exercises included on this worksheet and related 12.108 Electric Fields skill assessments:

Problem 1Difficulty: Mastery

Which rule set must every valid electrostatic field-line diagram follow?

ALines always form closed loops, cross at equilibrium points, and keep constant spacing.

BLines start on negative charge, end on positive charge, and ignore field strength.

CLines point opposite the force on a positive test charge and must be evenly spaced.

DLines start on positive charge, end on negative charge or infinity, never cross, and density represents strength.

Solution & Explanation:Electrostatic field lines represent the electric field direction and relative magnitude. They begin on positive charge, end on negative charge or infinity, cannot cross, and are denser where the field is stronger.

Problem 2Difficulty: Mastery

At point P, one electric-field contribution is 600 N/C north and another is 800 N/C west. What is the net electric field?

A1400 N/C, 45 degrees northwest.

B1000 N/C, 37 degrees north of west.

C1000 N/C, 53 degrees north of west.

D200 N/C, north.

Solution & Explanation:The perpendicular components form a 600-800-1000 right triangle. The angle from west toward north is tan^-1(600/800), about 37 degrees.

Problem 3Difficulty: Mastery

Four point-charge situations are compared at the same observation point: A has |q| = 2 microC and r = 1.0 m; B has |q| = 8 microC and r = 2.0 m; C has |q| = 1 microC and r = 0.50 m; D has |q| = 6 microC and r = 3.0 m. Which situation gives the strongest field?

ASituation A.

BSituation B.

CSituation C.

DSituation D.

Solution & Explanation:Compare |q|/r². A = 2, B = 8/4 = 2, C = 1/0.25 = 4, and D = 6/9. Situation C has the greatest proportional field strength.
