Question

2. Consider the collection of four charges B,C,D and E shown below. The magnitude of each charge is 1nC and the side of one small square is 0.2m. Remember that the electric potential is V=k(q/r).

What is the electric potential in J/C at point A due to charge C?

2. Consider the collection of four charges B,C,D and E shown below. The magnitude of each charge is 1nC and the side of one small square is 0.2m. Remember that the electric potential is V=k(q/r). What is the electric potential in J/C at point A due to charge C?

Explanation / Answer

due to charge C Potential at point A is = kq/r = 9*10^(9) *(- 1*10^(-9) )/ (5*0.2) = - 9 J/C
