Correct Answer : Option (D) : -3i + 11j + 7k
Explanation : Cross product of two vectors is, A X B = (a2*b3 – b2*a3)i – (a1*b3 – b1*a3)j + (a1*b2 – b1*a2)k. Using the formula, the answer can be calculated.
Correct Answer : Power radiated per unit solid angle in that direction
Correct Answer : A quarter wave line
