Step 1
The potential at point A is the sum of the potentials due to the two charges q1 and q2. The distance from q1 to A is 10 cm = 0.1 m. The distance from q2 to A is 10 cm = 0.1 m. The potential due to a point charge is given by $V = \frac{k q}{r}$, where $k = 8.99 Show moreā¦

Two point charges q1 = +2.55 nC and q2 = -6.80 nC are 0.100 mm apart. Point A is midway between them; point B is 0.080 mm from q1 and 0.060 mm from q2. (See Figure 1). Take the electric potential to be zero at infinity. Part a) Find the potential at point A. Express your answer in volts. Part b) Find the potential at point B. Express your answer in volts. Part c) Find the work done by the electric field on a charge of 2.20 nC that travels from point B to point A. Express your answer in joules to two significant figures.
