Question 1
A point charge of -3.9 micro-coulombs moves 1 meters directly towards a positively charged sheet (either directly with or against the field produced by the sheet, but you need to determine if it’s with or against the field). The magnitude of the electric field produced by the charged sheet is 6.5 x 106 N/C. What is the change in electric potential energy as the point charge moves in Joules? If the answer is negative, enter a negative sign, but do not enter a positive sign for positive answers.

Question 2
A point charge of -2.9 micro-coulombs moves 1.2 meters directly towards a negatively charged sheet (either directly with or against the field produced by the sheet, but you need to determine if it’s with or against the field). The magnitude of the electric field produced by the charged sheet is 9.3 N/C. What is the change in electric potential as the point charge moves in volts? If the answer is negative, enter a negative sign, but do not enter a positive sign for positive answers.

Question 3
At a point 2.17 meters from a point charge, the electric potential is found to be -14.8 x 103 volts. What is the point charge in micro-coulombs If the answer is negative, enter a negative sign, but do not enter a positive sign for positive answers.

Question 5
A point charge of +2.3 micro-coulombs moves 1.2 meters directly away from a positively charged sheet (either directly with or against the field produced by the sheet, but you need to determine if it’s with or against the field). The magnitude of the electric field produced by the charged sheet is 9.3 x 106 N/C. What is the change in kinetic energy as the point charge moves in Joules? Only include the electric force. If the answer is negative, enter a negative sign, but do not enter a positive sign for positive answers.

Question 6
A point charge of +5.6 micro-coulombs moves 0.8 meters parallel to a positively charged sheet. The magnitude of the electric field produced by the charged sheet is 6.3 x 106 N/C. What is the change in electric potential energy as the point charge moves in Joules? Only include the electric force. If the answer is negative, enter a negative sign, but do not enter a positive sign for positive answers.

Question 8
Four point charges of equal magnitude (absolute value) of +q, +q, +q, and -q all lie on the perimeter of a circle with a radius of 2 meters. The total potential at the center of the circle is 14 x 103 Volts. What is q in micro-coulombs (enter positive number… I want the absolute value)?

Question 9
Four point charges of equal magnitude (absolute value) of +q, +q, +q, and -q all at the corners of a square with sides of 2.6 meters. If q is 4.2 micro-coulombs, what is the total potential at the center of square in x 103 Volts or kilovolts?

Question 10
A point charge of -2.5 micro-coulombs moves from a point where the total potential (due to other charges) is 13 x 106 V to a point where the total potential is 22 x 106 V. What is the change of electric potential energy of the charge in Joules? If the answer is negative, enter a negative sign, but do not enter a positive sign for positive answers.
