The homogeneous gate shown in Fig. P2.122 consists of one quarter of a circular cylinder and is used to maintain a water depth of \(4 \mathrm{~m}\). That is, when the water depth exceeds \(4 \mathrm{~m}\), the gate opens slightly and lets the water flow under it. Determine the weight of the gate per meter of length.
