Really frustrated with this question!! can you help me!!
3 charges on (x,y) plane
q1(at origin) = 2nC
q2 (0,7) = -3nC
q3 (9,0) = -6nC
What is the magnitude of the resulting
force (in nano-Newtons) on the 2 nC charge
at the origin? The Coulomb constant is
8.98755 × 10
9
N · C
2
/m
.
Answer in units of nN
