An electron initially at rest, is accelerated through a potential difference of 200 volt, so that it acquires a velocity ${8.4 \times 10^6 m s^{-1}}$, the value of $e/m$ of electron will be

The work done by electric field during the displacement of a negatively charged particle towards a fixed positively charged particle is $9\, J$. As a result the distance between the charges has been decreased by half. What work is done by the electric field over the first half of this distance?

1000 similar electrified rain drops merge together into one drop so that their total charge remains unchanged. The electric energy gets increased by

Find out the effective capacitance between points A and B as shown in the figure. Here ${C_1 = C_2 = 20 \, \mu F }$ and ${C_3 = C_4 = 10 \, \mu F}$

Six equal capacitors each of capacitance C are connected as shown in the figure. Then the equivalent capacitance between A and B is

Two metal plate form a parallel plate capacitor. The distance between the plates is $d$. A metal sheet of thickness $d/2$ and of the same area is introduced between the plates. What is the ratio of the capacitances in the two cases?

The kinetic energy of an electron, which is accelerated in the potential difference of 100 V, is

Figure shows three spherical and equipotential surfaces A, B and C round a point charge The potential difference $V_A - V_B = V_B - V_C. \, If \, t_1 \, and \, t_2$ be the distances between them, then

Two spherical conductors $B$ and $C$ having equal radii and carrying equal charges in them repel each other with a force $F$ when kept apart at some distance. A third spherical conductor having same radius as that of $B$ but uncharged, is brought in contact with $B$, then brought in contact with $C$ and finally removed away from both. The new force of repulsion between $B$ and $C$ is
