r = d/2 = ½ m.
k =9•10^9 N•m²/C².
1.
E = 0,
Δφ = 2• k•q /r,
2.
E =2 •k•q /r²,
Δφ = 0
Two identical charges, q1 = q2 = 6.0 C, are separated by 1.0 m.
a. Calculate the electric field and electric potential difference at point P, midway between them.
b. Replace one of the charges with a charge of the same magnitude but opposite sign and repeat the calculation in (a).
c. (communication 4) Discuss your solutions.
