1.	A small wooden ball of density `rho` is immersed in water of density `sigma` to depth h and then released. The height H above the surface of water up to which the ball will jump out of water isA. `(sigmah)/(rho)`B. `((sigma)/(rho)-1)h`C. hD. zero
Answer» Correct Answer - B Work done against Buyonancy = gain of gravitational potential energy `(B-W)h=WH` `H=((B)/(W)-1)h" "implies H=((sigma)/(rho)-1)h`

Figure shows a cubical block of side 10 cm and relative density 1.5 suspended by a wire of cross sectional area `10^(-6) m^(2)`. The breaking stress of the wire is `7 xx 10^(6) N//m^(2)`. The block is placed in a beaker of base area `200 cm^(2)` and initially i.e. at t = 0, the top surface of water & the block coincide. There is a pump at the bottom corner which ejects `2 cm^(3)` of water per sec. Find the time at which the wire will break.

A necklace weighs `50 g` in air, but it weighs `46 g` in water. Assume that copper is mixed with gold to prepare the necklace. Find how much copper is present in it. (Specific gravity of gold is `20` and that of copper is `10`.)A. 10gB. 20gC. 30gD. None
Velocity of water in a river isA. Same everywhereB. More in the middle and less near its banksC. Less in the middle and more near its banksD. Increase from one bank to other bank
A large tank is filled with water to a height `H`. A small hole is made at the base of the tank. It takes `T_(1)` time to decrease the height of water to `(H)/(eta) (eta gt 1)`, and it takes `T_(2)` times to take out the rest of water. If `T_(1) = T_(2)`, then the value of `eta` isA. 2B. 3C. 4D. `2 sqrt(2)`
