Calculating Surface integral of A Vector field.

38 Views Asked by At

Find the surface integral of

$F(x,y,z) = x^2\hat{i}+ y^2\hat{j} -z\hat{k}$ around the triangle with vertices

$(0,0,0) , (0,2,0) , (0,0,3)$

So, the equation of that triangle is actually just the straight line

$3y +2z =6$ in $yz$ plane

now, Normal vector = $\hat{i}$

Using the formula

$\int F.\hat{n} ds = \int \int x^2 dydz$

But on $yz$ plane $x =0$ so Surface Integral is zero.

So, final answer is $0$ .

Is this correct ? Can someone please verify ?

Thank you.
