As shown in the figure. If value of `Q'` is Q/2, then what is the value of dielectric constant k?

For metals the value of dielectric constant (K) is

Assertion:- The reaction quotient Q, has the same presentation form as the equilibrium constant K and Q is evaluated using any given concentrations of the species involved in the reaction, and not necesssarily equilibrium concenetrations. Reason:- If the numerical value of Q is not the same as the value of equilibrium constant, that time reaction will never proceed.

Six charges are kept at the vertices of a regular hexagon as shown in the figure. If magnitude of force applied by +Q on +q charge is F, then net electric force on the +Q is nF. Find the value of n.

In the figure above what is the value of p+q?

Two identical capacitors 1 and 2 are connected in series to a batery as shown in figure. Capacitor 2 contains a dielectric slab of dieletric constant k as shown. Q_(1) and Q_(2) are the charges stored in the capacitors. Now the dielectirc slab us removed and the corresponding charges are Q'_(1) and Q'_(2) . Then

In the process shown in the figure on an ideal diatomic gas, the value of q and DeltaH respectively is

Three charges +q , +q, and Q are placed at the comers of a right angled isosceles triangle as shown in the figure. If the net potential energy of the system is zero then value of Q is

In the figure above, line k (not shown) is perpendicular to line j. If the equation of line k I s y=px , what is the value of constant p?

In the figure shown P_(2) and P_(2) are two conducting plates having charges of equal magnitude and opposite sign. Two dielectrics of dielectric constant K_(1) and K_(2) fill the space between the plates as shown in the figure. The ratio of electrical energy in 1^("st") dielectric to that in the 2^(nd) dielectric is :

A parallel plate capacitor has a dielectric slab of dielectric constant K between its plates that covers 1//3 of the area of its plates, as shown in the figure. The total capacitance of the capacitor is C while that of the portion with dielectric in between is C_1 . When the capacitor is charged, the plate area covered by the dielectric gets charge Q_1 and the rest of the area gets charge Q_2 . The electric field in the dielectric is E_1 and that in the other portion is E_2 . Choose the correct option/options, ignoring edge effects.
