In Millikan's oil drop experiment ,
The cylindrical tube of a spray pump has a cross-section of 8.0 cm^2 one end of which has 40 fine holes each of diameter 1.0 mm. If the liquid flow inside the tube is 1.5 m min^−1 ,
Two narrow bores of diameters 3.0mm and 6.0 mm are joined together to form a U-shaped tube open at both ends. If the U-tube contains water ,
what is the speed of ejection of the liquid through the holes ? ,
A voltmeter having resistance of `1800 Omega` is employed to measure the potential difference across `200 Omega` resistance which is connected to DC power supply of 50 V and internal resistance `20 Omega`. What is the percentage change in potential difference across `200 Omega` resistance as a result of connecting voltmeter across it ?

Two narrow bores of diameters 3.0mm and 6.0 mm are joined together to form a U-shaped tube open at both ends. If the U-tube contains water, what is the difference in its levels in the two limbs of the tube? Surface tension of water at the temperature of the experiment is 7.3×10^−2Nm^−1. Take the angle of contact to be zero. and density of water to be 1.0×10^3kg/m^3. (g=9.8ms^−2)
