Two charges `+- 10 muC` are placed `5xx10^(-3) m` apart. Determine the electric field at a point `Q, 0*15m` away from O, on a line passing through O and normal to the axis of the dipole.

Explanation

In the given problem. `r gt gt a` ltbgt
`:. E=1/(4pi epsi_(0)) p/r^(3)=1/(4pi epsi_(0))` or `E=9xx10^(9) xx(10xx10^(-6)xx5xx10^(-3))/(0.15xx0.15xx0.15) NC^(-1) =1.33xx10^(5) NC^(-1)`
