The figure below shows two small, charged beads separated by a distance of d-2.50 cm. The charges are a, -19.0 nC and q- 25.0 nC. Point 8 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.) 60.0* G (a) What is the electric potential (in kV) at point A x What is the electric potential at a point due to a single charged particle? Given more than one charged particle, how do you find the total potential at a point? How far is each charge from point A? Be careful with units and signs. Be sure to express your answer in units of kilovolts KV (b) What is the electric potential (in kV) at point 87 X Use the same method as used in part (a). How far is each charge from point 7 Be careful with units and signs. Be sure to express your answer in units of kilovolts KV
