0.2 F capacitor is charge to 600 V by a battery, on removing the battery, it is connected with another parallel plate condenser of I F . The potential decreases to

An uncharged capacitor with a solid dielectric is connected to a similar air capacitor charged to a potential of $V_0$. lf the common potential after sharing of charges becomes V, then the dielectric constant of the dielectric must be

Figure shows three points $A, B$ and $C$ in a region of uniform electric field $ \vec{E} $ . The line $AB$ is perpendicular and $BC$ is parallel to the field lines. Then which of the following holds good? where $V_A, V_B$ and $V_C$ represent the electric potential at the points $A, B$ and $C$ respectively.
