a point charge q is placed at origin.let Ea,Eb and Ec be the electric field at three points A(1,2,3),B(1,1,-1),C(2,2,2) due to charge q.then-a}Ea is perpendicular to Eb.b}Ea is parallel to Ebc}Eb=4Ecd}Eb=8Ec
Hi guys I`m from IIT Mumbai. Answer is A) because answer is EA perpendicular to EB Because the electric field acts along hte line joining hte point and the charge. so direction of EA is i+2j+3k that of EB is i+j-k dot product of EA and EB is 0. So they are at right angles.
