arranged q1 to q2 to q3 a is between q1 and q2 b is between q2
and q3
Let a=3 m, b=7 m, q1=2 C, q3=-3 C. What must q2 be for q1 to
feel no net force.
b)
Let a=3 m, b=8 m, q1=4 C, q2=5 C,
q3=-5 C. What is the magnitude of the electric field a
distance c=4 m vertically above q2 i.e. located at
(x,y)=(a,c)?
