A prism shaped styrofoam of density rho(...

A prism shaped styrofoam of density `rho_(styrofoam) (ltrho_(water))` is held completely submerged in water. It lies with its base horizontal. The base of foam is at depth `h_(0)` below water surface and atmospheric pressure is `P_(0)` Surface of water is open to atmosphere. Styrofoam prism is held in equilibrium by the string attached symmetrically as shown (Take `rho_(styrofoam)=rho_(f), rho_(water)=rho_(w))`.

Net force exerted by liquid on the styrofoam is

A

`sqrt(2)rhogL^(2)l`

B

`2rhogL^(2)l`

C

`rhog(L^(2)l)/2`

D

`rhog(l^(2)L)/2`

A prism shaped styrofoam of density rho_(styrofoam) (ltrho_(water)) is held completely submerged in water. It lies with its base horizontal. The base of foam is at depth h_(0) below water surface and atmospheric pressure is P_(0) Surface of water is open to atmosphere. Styrofoam prism is held in equilibrium by the string attached symmetrically as shown (Take rho_(styrofoam)=rho_(f), rho_(water)=rho_(w)) . Now string is cut and styrofoam is allowed to come to surface. A point mass is to be placed symmetrically on the upper surface of styrofoam such that it is in equilibrium with its base in horizontal plane. In equilibrium position styrofoam has half of its slant length submerged. Surface tension of water is T. contact angle is 0^(@). Determine mass m to achieve equilibrium.
