Please if your not sure dont answer i got it twice wrong already
.Four charged particles are placed so that each
particle is at the corner of a square. The sides
of the square are 14 cm. The charge at the upper left corner is 3 × 10−6 C, the charge at the
upper right corner is −7 × 10−6 C, the charge
at the lower left corner is −3.4 × 10−6 C,
and the charge at the lower right corner is
−9.2 × 10−6 C.
What is the magnitude of the net electric
force on the +3 × 10−6 C charge in the upper left corner? The value of the Coulomb
constant is 8.98755 × 109 N · m2

right and upward are positive.
Answer in units of N. What is the direction of this force (measured
from the positive x-axis as an angle between
−180◦
and 180◦
, with counterclockwise positive)?
