A cube made of wood having specific gravity `0.4` and side length `a` is floated in a large tanck full of water. Which action woukd change the depth to which block is submerged? `(gamma_("wood") lt gamma_("water"))`A. more water is added in the tankB. atmospheric pressure increasesC. the tank is accelerated upwardsD. A small coin is placed over the cube |
Answer» Correct Answer - D `mg = F_(b), a^(2) xx 0.4 rho g = a^(2) h rho g` `h = (2)/(5)a, m = a ^(3) xx 0.4, F_(net) =a^(2) x rho g` `T = 2pi sqrt((a^(3) xx 0.4 rho)/(a^(2) rho g)) , T = 2pi sqrt((2a)/(5g))` |
