The electric potential at a point (x,y,z) is given by `V=-s^(2)`A. `vecE=hati(2xy -z^(3))+hatj xy^(2)+hatk 3 z^(2)x `B. `vecE=hati(2xy +z^(3))+hatj x^(2)+hatk 3 xz^(2) `C. `vecE=hati 2xy + hatj (x^(2)+y^(2))+hatk(3xz-y^(2))`D. `vecE=hatiz + hatj xyz+ hatkz^(2)` |

Answer» Correct Answer - B `V=-x^(2)y-xz^(3)+4` `vecE=-V=-(hati(delta)/(deltax)+hatj(delta)/(deltay)+hatk(delta)/(deltaz)) (-x^(2)-xz^(3)+4)` `=(2xy+z^(3))hati+x^(2)hatj + 3xz^(2) hatk` |
