Q1/ Put (V) against the right sentences and (X) against wrong sentences then correct
the errors.
1. Electromagnetics (EM) may be regarded as the study of the interactions between
electric charges at motion.
2. The positive vector rp (or Radius Vector) of point P is defined as the displacement
from one point to another.
3. If two vectors A = 2a, - 3a, + a, and B=-4ax-2a, +5az. Then, A x B =
3.
4. For three vectors A, B, and C. A. So, A. (B x C) can be obtained by B(A.C)-
C(A. B) and A x (Bx C) by B. (CxA) C. (Ax B)
5. Both
vectors A = 3a, t 4y + a,
4a, - 3a, are mutually
perpendicular.
Q2/ Derive the vector transformation from Cartesian to Spherical (support your answer
using the drawing and equations).
Q3/ Given vector A 2a, + 3a, + 4a,, convert A into Cartesian coordinates at point (0,
2, -1).
Q4/ An infinite uniform line charges of 10nC/m lie along the (positive and negative) x and
z axes in free space. Find the electric field intensity at PA (0, 5, 5).
