2:07 PM webassign.net ..1 T-Mobile Wi-Fi 73% O No Need Help? en- -(2 points SerCP11 15 PD34 The figure below shows the electric field lines for two point charges separated by a small distance My Notes (a) Determine the ratio q1/q2 (b) What are the signs of q1 and q2? O q1 is positive O q1 is negative O 42 is positive O q2 is negative Need Help? Red -/13 points SerCP10 15.AE 00 My Notes EXAMPLE 15.3 A Charge Triangle GOAL Apply Coulomb's law in two dimensions. PROBLEM Consider three point charges at the corners of a triangle, as shown in the figure,Explanation / Answer
A.
Since we know that
q = e0*phi
phi = electric flux is directly proportional to electric field lines
q1/q2 = -N1/N2
N1, N2 = number of electric field lines
q1/q2 = -6/18 = -1/3
B.
We know that electric field lines originate at positive charge and ends at negative charge, So
So q1 is negative and q2 is positive.
