A capillary tube made of glass of radius 0.15mm is dipped vertically in a beaker filled with methylene iodide which rises to height h in the tube. It is observed that the two tangents drawn from liquid-glass interfaces (from opp. sides of the capillary) make an angle of 60∘ with one another. Then h is close to (surface tension =0.05 Nm^−1 density =667 kgm^−3 )(g=10ms^−2)

A 5μF capacitor is charged fully by a 220 V supply. It is then disconnected from the supply and is connected in series to another uncharged 2.5μF capacitor. If the energy change during the charge redistribution is X/100 J 100 then value of X to the nearest integer is ……

A circular coil of radius 10 cm is placed in a uniform magnetic field of 3.0 × 10^–5 T with its plane perpendicular to the field initially. It is rotated at constant angular speed about an axis along the diameter of coil and perpendicular to magnetic field so that it undergoes half of rotation in 0.2 s. The maximum value of EMF induced (in μV) in the coil will be close to the integer …..
