简答题

The charges q1 = 1.7 ´ 10–5 C, q2 = –1.9 ´ 10–4 C, and q3 = –3.7 ´ 10–4 C, are placed at the corners of the triangle shown below with a = 3 m, b = 3 m.  What is the absolute value of the potential at the location of the point charge q1? Use a value of 9 ´ 109 N.m2/C2 for Coulomb's constant, k.  Write your answer in the units of mega-volt (MV) to the nearest third decimal place, e.g. 6.327 Do not include units in your answer; just write the numerical value.  Please note: 1 MV = 106 V

The problem asks for the absolute value of the electric potential at the location of q1 due to the other charges q2 and q3 (the potential from q1 itself is not included). First, set up coordinates based on the diagram: place q1 at (0, a), q3 at (0, 0), and q2 at (b, 0). With a = 3......Login to view full explanation
