S.No.
1. Find the area inside the cardioid r = a(1+cosπœƒ) and outside the circle π‘Ÿ = π‘Ž .
2. Evaluate ∭ π‘₯𝑦𝑧𝑑π‘₯𝑑𝑦𝑑𝑧, where V is the volume given in the positive octant of the sphere
𝑉
𝑦2 + 𝑧2 = 1 .
π‘₯2 +
3. Show that 𝐹̅ =(𝑧 2 + 2π‘₯ + 3𝑦)𝑖̂ + (3π‘₯ + 2𝑦 + 𝑧)𝑗̂ + (𝑦 + 2𝑧π‘₯ )π‘˜Μ‚ is irrotational but not solenoidal.
Hence find its scalar potential.
4. Verify Green’s theorem in a plane with respect to ∫ π‘₯ 2 𝑑π‘₯ − π‘₯𝑦𝑑𝑦 , where C is the boundary of the
𝐢
square formed by π‘₯ = 0, 𝑦 = 0, π‘₯ = π‘Ž, 𝑦 = π‘Ž .
5. Verify the Stoke’s theorem for 𝐹̅ = (𝑦 − 𝑧 + 2)𝑖̂ − (𝑦𝑧 + 4)𝑗̂ − (π‘₯𝑧)π‘˜Μ‚ over the surface of a cube
π‘₯ = 0, 𝑦 = 0, 𝑧 = 0, π‘₯ = 2, 𝑦 = 2, 𝑧 = 2 above the XOY plane.
