Test: Curl - Question 1
Save

Curl is defined as the angular velocity at every point of the vector field. State True/False. 

Detailed Solution: Question 1

Answer: a
Explanation: Curl is defined as the circulation of a vector per unit area. It is the cross product of the del operator and any vector field. Circulation implies the angular at every point of the vector field. It is obtained by multiplying the component of the vector parallel to the specified closed path at each point along it, by the differential path length and summing the results.

The curl of curl of a vector is given by, 

Detailed Solution: Question 2

Answer: b
Explanation: Curl (Curl V) = Grad (Div V) – (Del)2V is a standard result of the curl operation.

Which of the following theorem use the curl operation?

Detailed Solution: Question 3

Answer: c
Explanation: The Stoke’s theorem is given by ∫ A.dl = ∫Curl(A).ds, which uses the curl operation. There can be confusion with Maxwell equation also, but it uses curl in electromagnetics specifically, whereas the Stoke’s theorem uses it in a generalised manner. Thus the best option is c.

Test: Curl - Question 4
Save

The curl of a curl of a vector gives a

Detailed Solution: Question 4

Answer: b
Explanation: Curl is always defined for vectors only. The curl of a vector is a vector only. The curl of the resultant vector is also a vector only.

Test: Curl - Question 5
Save

Find the curl of the vector and state its nature at (1,1,-0.2)F = 30 i + 2xy j + 5xz2 k

Detailed Solution: Question 5

Answer: d
Explanation: Curl F = -5z2 j + 2y k. At (1,1,-0.2), Curl F = -0.2 j + 2 k. |Curl F| = √(-0.22+22) = √4.04.

Test: Curl - Question 6
Save

 Is the vector is irrotational. E = yz i + xz j + xy k 

Detailed Solution: Question 6

Answer: a
Explanation: Curl E = i(Dy(xy) – Dz(xz)) – j (Dx(xy) – Dz(yz)) + k(Dx(xz) – Dy(yz)) =
i(x – x) – j(y – y) + k(z – z) = 0
Since the curl is zero, the vector is irrotational or curl-free.

Test: Curl - Question 7
Save

 Find the curl of A = (y cos ax)i + (y + ex)k

Detailed Solution: Question 7

Answer: b
Explanation: Curl A = i(Dy(y + ex)) – j (Dx(y + ex) – Dz(y cos ax)) + k(-Dy(y cos ax))
= 1.i – j(ex) – k cos ax = i – ex j – cos ax k.

Test: Curl - Question 8
Save

Find the curl of the vector A = yz i + 4xy j + y k

Detailed Solution: Question 8

Answer: d
Explanation: Curl A = i(Dy(y) – Dz(0)) – j (Dx(0) – Dz(yz)) + k(Dx(4xy) – Dy(yz)) =
i + y j + (4y – z)k, which is option d.

Test: Curl - Question 9
Save

Curl cannot be employed in which one of the following?

Detailed Solution: Question 9

Answer: d
Explanation: In the options a, b, c, the EM waves travel both in linear and angular motion, which involves curl too. But in waveguides, as the name suggests, only guided propagation occurs (no bending or curl of waves).

Test: Curl - Question 10
Save

Which of the following Maxwell equations use curl operation?

Detailed Solution: Question 10

Answer: a
Explanation: Maxwell 1st equation, Curl (H) = J (Ampere law)
Maxwell 2nd equation, Curl (E) = -D(B)/Dt (Faraday’s law)
Maxwell 3rd equation, Div (D) = Q (Gauss law for electric field)
Maxwell 4th equation, Div (B) = 0(Gauss law for magnetic field)
It is clear that only 1st and 2nd equations use the curl operation.
