1.	A U-tube of base length l filled with same volume of two liquids of densities `rho " and " 2rho` is moving with an acceleration a on the horizontal plane. If the height difference between the two surfaces (open to atmosphere) becomes zero, then height h is given by A. `(al)/(g)`B. `(3al)/(2g)`C. `(2gl)/(3g)`D. `(al)/(2g)`
Answer» Correct Answer - B Writing presure equation from one end to other end of tube. `p_(0)+2rho gh-2rho. (l)/(2). A-rho(l)/(2). A-rho gh=p_(0)` `therefore " " h=(3al)/(2g)`

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 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)`
