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.
