Problem 23.8: Find the unknown charge
Please wait for the animation to completely load.
The charge on A is 1 nC and the charge on B is -3 nC (position is given in meters and electric field strength is given in newtons/coulomb). Restart.
- Where does the unknown charge (movable) need to be placed for the electric field at the origin (where the black dot is) to be zero?
- What is the charge on the unknown charge?
