Question
Three charges are held in place in the xy-plane.
Three charges are held in place in the xy-plane.
q = 9.39 nC and L = 2.93 cm. If it requires 0 J of energy to move Charge D (charge = +2q) from at rest infinitely far away to at rest at the origin, what is the charge of Charge C? Write your answer (take care of include positive or negative) to three significant figures and write them in the number of nanoCoulombs
part. 2
Choose all of the following that are accurate regarding the electric field at the origin due to thre three source charges (A, B and C). You should have two answers in total. (You do not have to calculate the electric field in full, a well-labeled picture should suffice to answer this question correctly.)
The x-component of the electric field is positive
The x-component of the electric field is zero
The x-component of the electric field is negative
The y-component of the electric field is positive
The y-component of the electric field is zero
The y-component of the electric field is negative
The x-component of the electric field is positive
