A point charges +10 mu Cis a distance5 cm directly above centre of a square of side 10 cm as shown in What is the magnitude ofthe electric flux through the square? |
|
Answer» SOLUTION :To find the electric flux consider an IMAGINARY CUBE of side 10 cm such that the charges of `+10 muC ` is located at the centre of cube. Now in accordance with Gauss theorem, total electric flux over the entire `phi_E =(q)/(in_0)=(10xx10 ^(-6))/(8.85xx10^(-12))=1.13 xx 10^(5)N m^(2)C^(-1) ` As chargesis situated at the centre of teh cube having six surface in all and the given square is one of thesesix, HENCE electric flux through the given square ` =(1)/(6) phi_in =(1.13xx10^(6))/(6) =1.9 xx10 ^(5)Nm^(2) C^(-1) `
