Electric Field inside a Conductor under Electrodynamic Conditions

Q. Three point charges, $1\text{C}$, $2\text{C}$ and $3\text{C}$ are placed at the corners of an equilateral triangle of side $100\text{cm}$. Find the work done to move these charges to corners of similar triangle of side $50\text{cm}$.

1. ${10}^{12}\text{J}$
2. ${10}^{11}\text{J}$
3. ${10}^{13}\text{J}$
4. ${10}^{10}\text{J}$

Q.
$r_1=1m$
$r_2=2m$
$r_3=3m$

Figure shows some equipotential surfaces [Spherical in shape]

1. Electric field in the region is directed radialy outwards.
2. Magnitude of electric field is $E=6r$
3. Magnitude of electric field is $E=\frac{6}{r^2}$
4. Electric field decreases as we move radialy outwords.

Q. Satrajit had learned in electrostatics that the electric field inside a conductor is always zero. Now they are telling him that when current flows, an electric field gets set up inside a conductor which drifts the electrons, thus making the current flow. This makes no sense to him.
It makes no sense to him because

1. They are telling him some random things which has no science in it
2. He doesn’t understand that electric field inside a conductor is zero only under electrostatic conditions
3. He thinks electric field is non conservative.
4. He thinks electric field is not a vector.
