In the figure above, q1 = 3.00q and q2 = -q, where q = 0.01 µC, d1 = 7.13 cm, d2 = 10.70 cm, θ1 = 51.0 ° and θ2 = 63.0 °. How much work is done by the electric field as a charge Q = +4q is brought from infinity along the path to the point shown in the figure?
Homework Answers
at infinity, Potential Vi = 0
at the given location,
Vf = k q1 / d1 + k q2 / d2
= ( 9 x 10^9)[ (3 x 0.01 x 10^-6)/(0.0713) + (-0.01 x 10^-6)/0.1070 ]
= 2946 Volt
Work done by electric field = - delta(PE)
= -q (VF - Vi )
= - 4 x 0.01 x 10^-6 x 2946
= - 117.8 x 10^-6 J
