A square surface of side $L\text{m}$ is in the plane of the paper. A uniform electric field $E(\text{V/m})$, also in the plane of the paper, is limited only to the lower half of the square surface, (see figure). The electric flux in SI units associated with the surface is :

A tube of length $L$ is filled completely with an incompressible liquid of mass $M$ and closed at both ends. The tube is then rotated in a horizontal plane about one of its ends with a uniform angular velocity $\omega$. The force exerted by the liquid at the other end is:

A uniform rod of length $l$ and mass $M$ is free to rotate in a vertical plane about A. The rod initially in the horizontal position is released. The initial angular acceleration of the rod is: (Moment of inertia of the rod about A is $\frac{M{l}^2}{3}$)

The vectors $\vec{a}$ and $\vec{b}$ are such that:$|\vec{a}+\vec{b}|=|\vec{a}-\vec{b}|$ The angle between the two vectors is :

Two bodies, A (of mass $1\text{kg}$) and B (of mass $3\text{kg}$) are dropped from heights of $16\text{m}$ and $25\text{m}$, respectively. The ratio of the time taken by them to reach the ground is :
