AIPMT 2012 Mock Test

A parallel plate capacitor has a uniform electric field $E$ in the space between the plates. If the distance between the plates is $d$ and area of each plate is $A$, the energy stored in the capacitor is:

The power dissipated in the circuit shown (two $10\Omega$ resistors in parallel connected to $R$ in series, $10\text{V}$ battery) is $30\text{Watts}$. The value of $R$ is:

If $v_e$ is escape velocity and $v_o$ is orbital velocity of a satellite for orbit close to the earth’s surface, then these are related by:

A stone is dropped from a height $h$. It hits the ground with a certain momentum $P$. If the same stone is dropped from a height $100\%$ more than the previous height, the momentum when it hits the ground will change by:

An ideal gas goes from state $A$ to state $B$ via three different processes. If $Q_1,Q_2,Q_3$ indicate the heat absorbed and $\Delta U_1,\Delta U_2,\Delta U_3$ indicate the change in internal energy:
