(need both parts answered)

The image shows a small charge (qs 25.0 nC) set at a distance r 0.644 m from a larger charge. The electric potential (Vi) at the location of qs is 0.0522 V Answer the two questions below, using three significant figures. Part A: What is the value of the electric potential (V2) at the distance r2 = 0.322 m? Number ri V2 = Part B: If the small charge qs is moved along the path s from r to r2, how much work (W) must be done to the charge qs? Number

Explanation / Answer

part A :

electric potential V = KQ/r

V = (9e9 * 25 e -9)/(0.322)

V = 698.75 Volts

-------------------------------------

part B :

Work Done W = Vq

W = 698.75 * 25 e-9

W = 17.46 micro joules
