List of top Physics Questions on Electric Field asked in AIPMT

The electric potential $V$ at any point $(x, y, z)$, all in metres in space is given by $V = 4x^2$ volt. The electric field at the point $(1, 0, 2)$ in volt/meter, is

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