Question: Two point charges q = 2106 C and q2=-1106 C are at a distance r = 1 m and r2 = 2 m from

Two point charges q1 = 2x10-6 C and q2 = -1106 C are at a distance r = 1 m and r2 = 2 m from a point P

Two point charges q = 2106 C and q2=-1106 C are at a distance r = 1 m and r2 = 2 m from a point P respectively as shown in the figure below. (Take ke = 9 x 10' N.m/C) (a) Calculate the total electric potential due to charges qi and 92 at point P. (Vp=?) (b) A third charge 93 = -1108 C is placed at point P. Determine the work Wother required to move the charge q3 from P to infinity. (At infinity V = 0 and KE = 0) 93=-110-8 C + = 1m x (Vp=?) 91-210-6 C 2=2m 92--110C
