AIEEE 2008 PYQ Mock Test

A capillary tube (A) is dipped in water. Another identical tube (B) is dipped in soap water solution. Which of the following shows the relative nature of the liquid columns?

Suppose an electron is attracted towards the origin by a force $k/r$ where $k$ is a constant. By applying Bohr model, the radius $r_n$ and kinetic energy $T_n$ of the $n^{\text{th}}$ orbital are:

A wave is described by $y(x,t)=0.005\cos (\alpha x-\beta t)$. If the wavelength and time period are $0.08\text{m}$ and $2.0\text{s}$ respectively, then $\alpha$ and $\beta$ are:

Two coaxial solenoids are made on a pipe of area $A=10{\text{cm}}^2$ and length $L=20\text{cm}$. If solenoids have $N_1=300$ and $N_2=400$ turns, their mutual inductance is (${\mu }_0=4\pi \times 10^{-7}\text{Tm/A}$):

A circuit has two inputs A and B and output C. The truth table shows C is 0 only when both A and B are 0, and C is 1 otherwise. This circuit represents:
