The value of electric field intensity is 4.9 x 10^-10 N / C
Explanation:
Given data:
q1 = 3.2×10-19 C
q2 = -3.2×10-19 C
Distance between charged "d" 2.4 m
As we know that
F = Kq1q2 / d^2
E = F / Q
E = Q1 / 4πεod^2
E = 3.2×10-19 / 4 x 3.14 x 8.854 × 10^-12 (2.4)^2
E = 3.2 x 10^-19+12 / 4 x 3.14 x 8.854 x 5.76
E = 3.2 x 10^-7 / 640.55
E = 0.0049 x 10^-7
E = 4.9 x 10^-3-7 = 4.9 x 10^-10 N / C
Thus the value of electric field intensity is 4.9 x 10^-10 N / C

Answer:
U=−3×10−23J
Explanation:
Potential energy of electric dipole
U=−pEcosθ=−(q×2l)Ecosθ
U=−(3.2×10−19×2.4×10−10)4×105cosθ
U=−3×10−23J (approx.)
