Imagine an electric charge  is placed at a point  in an electric field of a charge . An external force acts on the charge  and moves it from point  to point . The displacement from point  to point  is . The work done by the external force on the charge : (select all that apply)

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

If the potential due to a point charge is 709 V at a distance of 11.8 m, what is the magnitude of the charge? Use a value of 9.00x109 N.m2/C2 for Coulomb's constant, k.  Write your answer in the units of micro-coulomb ( 𝜇 𝐶 ) to the third decimal place, e.g. 1.263 Do not include units in your answer; just write the numerical value.
