Problem

A point charge q is placed at origin. Let

\vec{E}_A, \vec{E}_B

and

\vec{E}_C

be the electric field at three points A (1, 2, 3), B (1, 1, -1) and C (2, 2, 2) due to charge q. Then [i]

\vec{E}_A \perp \vec{E}_B

[ii]

|\vec{E}_B| = 4|\vec{E}_C|

select the correct alternative (a) only [i] is correct (b) only [ii] is correct (c) both [i] and [ii] are correct (d) both [i] and [ii] are wrong
