A point charge +10mu C is at a distance 5 cm directly above the centre of a square of side 10 cm, as shown in figure. What is the magnitude of the electric flux through the square? (Hint: Think of the square as one face of a cube with edge 10cm) |

Answer» Solution :`phi=1/epsi_(0) Q=(1 xx 10 xx 10^(-6))/(8.85 xx 10^(-12)) =1.13 xx 10^(6) NM^(2) C^(-1)` Flux through the square `=(1.13 xx 10^(6))/(6) =1.88 xx 10^(5)Nm^(2) C^(-1)` |
