Two charges $$\pm10~\mu\text{C}$$ are placed $$5.0$$ mm apart. The electric field at a point $$P$$ on the axis of the dipole $$15$$ cm away from its centre $$O$$ on the side of the positive charge, as shown in the figure is:

1. $$2.7\times10^5~\text{NC}^{-1}$$
2.
$$4.13\times10^6~\text{NC}^{-1}$$
3. $$3.86\times10^6~\text{NC}^{-1}$$
4. $$1.33\times10^5~\text{NC}^{-1}$$

Two charges $$\pm 10~ \mu \text{C}$$ are placed $$5.0$$ mm apart. The electric field at a point $$Q$$, $$15$$ cm away from O on a line passing through $$O$$ and normal to the axis of the dipole, as shown in the figure is:

1. $$2.8 \times 10^5~\text{NC}^{-1}$$
2. $$3.9\times 10^5 ~\text{NC}^{-1}$$
3. $$1.33\times 10^5 ~\text{NC}^{-1}$$
