Question

# The given diagram shows two infinite line of charges having equal (in magnitude) linear charge density but with opposite sign. The direction of electric field at any point on x-axis for ( (x>0) ) is given by the unit vect(A) ( cos theta hat{mathrm{i}}+sin theta hat{mathrm{j}} )(B) ì(C) j(D) ( -sin theta hat{i}+sin theta hat{j} )

from the tignec component of electric field due to positive charge along ( x ) -anis in
[
=f cos (90-theta)=sin theta
]
component of elective field due to - re is along - ue x ans and is equal fo
chage
[
=E sin theta
]
So het electric field along Xaris in 0 component of electric field due to twe
( y ) an
[
=E cos theta
]
So net fiel is along the ( y ) anis the is ( (c) hat{jmath} )
