Dima pulls directly backward with a force ?=137 N on the end of a 2.00 m -long oar. The oar pivots about its midpoint. At the instant shown, the oar is completely in the ??- plane and makes a 30.0∘ angle with respect to the water's surface. Derive an expression for the torque vector ?⃗ about the axis through the oar’s pivot. Express the torque using ??? vector notation. ?⃗=???+???+??? I got this as the answer but it is still wrong. Please help me.

Center of Gravity of a system

The centre of gravity is a property that is based on the geometry of a rigid body or any particle. It is described as an equilibrium point or a hypothetical location where the total weight of the body is concentrated.
