Question

When the water surface coincides with the top edge of a rectangular vertical gate 40 m (wide) $\times$ 3 m (deep), then the depth of centre of pressure is

• A. 1 m
• B. 1.5 m
• C. 2 m
• D. 2.5 m

Answer 1

The correct option is C 2 m

Depth of centre of pressure,
$h_p=\frac{2d}{3}=\frac{2\times 3}{3}=2m$
