in the Figure below, q = 2 nC, r1 = 7 cm, and r2 = 14 cm. (a) What is the electric potential at points A, B, and C?in units of V (b) What is the potential energy of an electron at each of these points? in units of J
(c) What are the following potential differences? in units of V
(a) What is the electric potential at points A, B, and C? in units of V (b) What is the potential energy of an electron at each of these points? in units of J (c) What are the following potential differences? in units of V in the Figure below, q = 2 nC, r1 = 7 cm, and r2 = 14 cm.
Explanation / Answer
q = 2 nC, r1 = 7 cm, and r2 = 14 cm. (a) What is the electric potential at points A, B, and C? in units of V electric potential at A=9*10^9*2*10^-9/7*10^-2 V solving we will get the answer. similarly solve the potential for other points. (b) What is the potential energy of an electron at each of these points? in units of J potential energy=9*10^9*2*10^-9*1.6*10^-19/7*10^-2 J similarly solve the potential energy for other points. (c) What are the following potential differences? in units of V as we arrive at the potentials at respective points in case potential difference=difference between potentials between corresponding points.
