Curl Question 7:
curl(grad φ) =
Answer (Detailed Solution Below)
Curl Question 7 Detailed Solution
Explanations:
The curl of the gradient of any scalar function φ is always zero. curl(grad φ) = 0
Curl Question 8:
Determine the curl (grad ϕ), where ϕ = x3 + y3 + z3 – 3xyz______
Answer (Detailed Solution Below) 0
Curl Question 8 Detailed Solution
Explanation:
Curl grad ϕ = ∇ × ∇ϕ
According to property of Nable operator (∇)
∇ × ∇ϕ = 0
Where, ϕ is a scalar quantity
Thus, curl (grad ϕ) = 0

Curl Question 10:
A vector field with a vanishing curl is known as _______
Answer (Detailed Solution Below)
Curl Question 10 Detailed Solution
A vector field with a vanishing curl is called an irrotational vector.
Explanation:
Irrotational Vector: A vector point function F is said to be a rotational vector if curl F = 0
curl F = ∇ × F =
Additional Information
If a vector point function F(x, y, z) = F1i + F2j + F3k is defined and differentiable at each point in some region of space then the divergence of F is denoted by div F or ∇.F and define as,
div F = ∇.F =
Solenoidal Vector: A vector function F is said to be a solenoidal vector if ∇.F = 0.
