`l=300mm=30cm=3` decimeter, `theta=10^(@),[alpha]_(A)^(T)=60^(@)`, volume of solution `=60cm^(3)`
`theta=[alpha]_(lamda)^(T)lCimpliesC=(theta)/([alpha]_(lamda)^(T)l)=(10^(@))/(60^(@)xx3)=(1)/(18)gcm^(-3)`
Quantity of sugar contained `=(1)/(18)xx60=3.33g`

An experimental setup of verification of photoelectric effect is shown in the diagram. The voltage across the electrode is measured with the help of an ideal voltmetar, and which can be varied by moving jockey 'J' on the potentiometer wire. The battery used in potentiometer circuit is of 20 V and its internal resistance is 2omega . The resistance of 100 cm long potentiometer wire is 8 omega . The photo current is measured with the help of an ideal ammeter. Two plates of potassium oxide of area 50 cm^(2) at separation 0.5 mm are used in the vacuum tube. Photo current in the circuit is very small so we can treat potentiometer circuit an indepdent circuit. The wavelength of various colours is as follows : |{:("Light",underset("Violet")(1),underset("Blue")(2),underset("Green")(3),underset("Yellow")(4),underset("Orange")(5),underset("Red")(6)),(lambda "in" Årarr,4000-4500,4500-5000,5000-5500,5500-6000,6000-6500,6500-7000):}| It is found that ammeter current remians unchanged (2muA) even when the jockey is moved from the 'P' to the middle point of the potentiometer wire. Assuming all the incident photons eject electron and the power of the light incident is 4 xx 10^(-6) W . Then colour of the incident light is :

The specific conductivity of a solution containing 1.0g of anhydrous BaCl_(2) in 200 cm^(3) of the solution has been found to be 0.0058 S cm^(-1) . Calculate the molar and equivalent conductivity of the solution. Molecular wt. of BaCl_(2) = 208 [mu implies lambda_(m)]

Two liquids A and B form an ideal solution. At 300 K , the vapour pressure of a solution containing 1 mol of A and 3 mol of B is 550 mm Hg . At the same temperature, if 1 mol more of B is added to this solution, the vapour pressure of the solution increases by 10 mm Hg . Determine the vapour pressure of A and B in their pure states.

As shown in the figure two cylindrical vessels A and B are interconnected . Vessel A contains water up to 2m height and vessel B contains kerosene . Liquids are separated by movable, airtight disc C . If height of kerosene is to be maintained at 2m , calculate the mass to be placed on the piston kept in vessel B. Also calulate the force acting on disc C due to this mass. Area of piston =100cm^(2) , area of disc C=10cm^(2) , Density of water =10^(3)kgm^(-3) , specific density of kerosene =0.8 .
