There are two infinite plane sheets each having uniform surface charge density `+sigma C//m ^(2)` They are inclined to each other at an angle `30^(@ )`as shown in the figure. Electric field at any arbitrary point P is:

Options

A. ` ( sigma ) /( 2 in _ 0 ) [ ( 1 + (sqrt 3)/2 ) haty - ( hatx ) /(2) ] `
B. ` ( sigma ) /( 2 in _ 0 ) [ ( 1 - ( sqrt3) /( 2 ) ) haty - ( hatx ) /(2) ] `
C. ` (sigma ) /( 2 in _ 0 ) [ ( 1 -(sqrt 3)/2 ) haty + ( hatx ) /(2) ] `
D. ` ( sigma ) /( in _ 0 ) [ ( 1 + ( sqrt3 ) /( 2 ) ) haty + ( hatx ) /(2) ] `
