Four charges $2C, -3C, -4C$ and $5C$ respectively are placed at all the corners of a square. Which of the following statements is true for the point of intersection of the diagonals ?
See the diagram . Area of each plate is $2.0\ m^2$ and $d = 2 \times 10^{-3}\ m$. A charge of $8.85 \times 10^{-8}\ C$ is given to $Q$. Then the potential of $Q$ becomes......$V$
A $60\; pF$ capacitor is fully charged by a $20\; \mathrm{V}$ supply. It is then disconnected from the supply and is connected to another uncharged $60 \;pF$ capactior is parallel. The electrostatic energy that is lost in this process by the time the charge is redistributed between them is (in $nJ$)
Two capacitors $C_1$ and $C_2=$ $2 C _1$ are connected in a circuit with a switch between them as shown in the figure.Initially the switch is open and $C _1$ holds charge $Q$. The switch is closed. At steady state, the charge on each capacitor will be
A capacitor is charged with a battery and energy stored is $U$. After disconnecting battery another capacitor of same capacity is connected in parallel to the first capacitor. Then energy stored in each capacitor is
A dipole consisting of two charge $\pm q$ separated by a distance $2 a$ is placed with its centre $D$ away from the center of a grounded sphere of radius $R ( D > > a )$. When the dipole moment vector is perpendicular to the line joining the two centres (those of the dipole and sphere) the charge induced on the sphere is
A particle $A$ has charge $+q$ and particle $B$ has charge $+ 4q$ with each of them having the same mass $m$. When allowed to fall from rest through same electrical potential difference, the ratio of their speed $V_A : V_B$ will be :-
A charged capacitor is allowed to discharge through a resistor by closing the key at the instant $t =0$. At the instant $t = (ln \,4) $ $\mu s$, the reading of the ammeter falls half the initial value. The resistance of the ammeter is equal to
