A cube placed in vacuum contains a charge of ` 9 xx 10^( - 9 ) C `. What will be the electric flux linked with each face of the cube ?

Explanation

Electric flux linked with the 6 faces of the cube ` = ( q ) /( in _ 0` ) . Due to symmetry, this flux is equally shared among the 6 faces. So, the electric flux linked with each face of the cube
` = (1 ) /( 6 ) * ( q ) /( in _ 0) = ( 1 ) /( 6 ) xx ( 9 xx 10 ^( - 9))/( 8.854 xx 10 ^( - 12 )) `
` = 169.41 V* m`
