Question

The figure below shows two small, charged beads separated by a distance of d= 3,00 cm. The charges are q, = -17.5 nC and q, = 28.5 nC. Point B is at the midpoint between the two charges, and point A is at
the peak of an equilateral triangle, with each side of length d, as shown. (Assume the zero of electric potential is at infinity.)
d
160.0°
(a) What is the electric potential (in kV) at point A?
kV
(b) What is the electric potential (in kV) at point B?
kV

Expert Solution

Step 1

The electric potential due to a charge q at some distance r from it is given by-
$\Rightarrow V = \frac{1}{4 {πε}_{0}} \frac{q}{r}$
where, $\frac{1}{4 {πε}_{0}} = 9 \times 10^{9} {Nm}^{2} / C^{2}$
