AIPMT 2011 Preliminary Mock Test

The dimensions of $({\mu }_0{ϵ}_0{)}^{-1/2}$ are:

The moment of inertia of a thin uniform rod of mass $M$ and length $L$ about an axis passing through its midpoint and perpendicular to its length is $I_0$. Its moment of inertia about an axis passing through one of its ends and perpendicular to its length is:

A boy standing at the top of a tower of $20\text{m}$ height drops a stone. Assuming $g=10{\text{ms}}^{-2}$, the velocity with which it hits the ground is:

A person of mass $60\text{kg}$ is inside a lift of mass $940\text{kg}$ and presses the button on the control panel. The lift starts moving upwards with an acceleration $1.0{\text{m/s}}^2$. If $g=10{\text{ms}}^{-2}$, the tension in the supporting cable is:

A body projected vertically from the earth reaches a height equal to the earth's radius before returning to the earth. The power exerted by the gravitational force is greatest:
