New Problems reloads the page with new variable values in all questions. You must do this after grading the test to rework it another time.
Make sure to enter your answers in the specified units .

1
Two objects m apart both have the same charge. If the force on one of them is N what is the charge (in µC ) on the object?
2
The electric field intensity m away from a charged sphere is N/C. What charge (in µC) has been added to the sphere?
3
How much work (in J) is required to move 1.6 mC of charge from a distance of m to a distance m from a charge of µC?
4

Three charges are fixed as shown, with Q1 = - µC, Q2 = µC, and Q3 = µC. How many degrees below the x axis is the force on a proton located at point P?

5
An electron (q = 1.6 x 10-19C; m =9.11 x 10-31 kg) accelerates from rest through a potential difference of V. What is the electron's final speed (in m/s)?
