For a vector field \overrightarrow{\A}, Which one of the following is false

Correct Answer is : A→ is irrotational if ∇2×A→=0

∇ \times\overrightarrow{\A} in another vector field

∇ \times(∇ \times\overrightarrow{ {\A}})=∇(∇ \cdot \overrightarrow{ {\A}})-∇^{2} {\A}^{2}

\overrightarrow{ {\A}} is irrotational if ∇^{2} \times \overrightarrow{ {\A}}=0

\overrightarrow{\A} is sinusoidal if \A ^{\to} ssinusoidalif ∇ \cdot \overrightarrow{\A}=0
