Question

An electric dipole consists of two charges + 10 UC and -10 UC separated by a distance of 5 mm. Calculate the electric field at a point on the axial line due to the dipole at a distance of 10 cm from the centre of the dipole?

Answer 1

Answer:

9×10^5

Explanation:

E=[2P÷r^3]×9×10^9

2a<<<<<r

P=q×2a

=10×10^-6×5×10^-3=5×10^-8

E=[2×5×10^-8÷(0.1)^3×9×10^9=1.5×10^-23
