Two protons (p) and two
(e) are arranged on a circle of
5 [cm], with angles 0₁ = 20°,
0₂ = 60°, 03 = 20° and 04 = 60°, as
shown in the figure. (qp = +1.6 x 10-19
[C] and qe = -1.6 × 10-19 [C]). The figure
is not to scale.

a.
Find Enet, the net electric field
vector produced at the center of the circle.
Enet = ([
])i + (
]) Ĵ [N/C]
b.
Where on the circle should a
fifth point charge qo be placed (give its
angle relative the +x-axis) and what is its
value (calculate qo) in order to have Ēnet
(the net electric field at the center of the
circle) equals zero (Type the detailed
