2.30 Let r denote a position vector r = x = xiêį (r² = x₂x₁) and A be an arbitrary constant
vector. Use index notation to show that:
(a)
(c)
² (r) = n(n+1) rn-2.
V. (rx A) = 0.
(b)
(d)
V(r. A) = A.
▼x (rx A) = -2A.

A net is dipped in a river. Determine the flow rate of water across the net if the velocity vector field for the river is given by
v = (x-y, z + y + 3, z²) and the net is decribed by the equation y = √1-x²-2², y ≥ 0, and oriented in the positive y-
direction.
