Correct Answer : Option (C) : –i – j – k
Explanation : The curl of y i + z j + x k is i(0-1) – j(1-0) + k(0-1) =-i –j –k. Since the curl is zero, the value of Stoke’s theorem is zero. The function is said to be irrotational.
Correct Answer : Power radiated per unit solid angle in that direction
Correct Answer : A quarter wave line
Correct Answer : Larger wavelength than in the free space
