Homework Answers
9) C- vector product is not commuative but dot product is.
10)C- because it consists of addition vector and scalar which is not possible.
11)B- this is derivative in direction of each axis
12)D- beause y and z are constant so it is perpendicular to yz plane
and it is in xy plane
13)b- magnitude of field is inversely proportional to square of distance so it wiil be multiplied by 1/4
14) a -normal parts of electric filed are not equal only tangential components are equal.
