In an experiment of Wheatstone bridge, a null point is obtained at the centre of the bridge wire. When a resistance of $10 \, \Omega $ is connected in one gap, the value of resistance in other gap is
Electric potential of earth is taken zero. No electric field exists on earth surface.
A radioactive nucleus is being produced at a constant rate $\alpha$ per second. Its decay constant is $\lambda$. If $N_0$ are the number of nuclei at time t = 0, then the maximum number of nuclei possible are
A conducting rod of length $l$ and mass $m$ is moving down a smooth inclined plane of inclination $\theta$ with constant velocity $v$. A current $i$ is flowing in the conductor in a direction perpendicular to paper inwards. A vertically upwards magnetic field $\vec{ B }$ exists in space. Then magnitude of magnetic field $\vec{ B }$ is
For a dilute solution, Raoult's law states that
The bob of a simple pendulum is a ball full of water, if a fine hole is made in the bottom of the ball, the time period first increases and then decreases. As water flows out of the bob the weight of bob decreases.
Which of the following statements about Spirogyra is correct?
To a $25 \,ml \,H _{2} O _{2}$ solution, excess of acidified solution of KI was added. The iodine liberated required $20\, ml$ of $0.3 \,N \,Na _{2} S _{2} O _{3}$ solution.
What is the molarity of $H _{2} SO _{4}$ solution that has a density of $1.84\, g / cc$ at $35^{\circ} C$ and contains $98 \%$ by weight?
Four charges are arranged at the corners of a square as shown in the figure. The direction of electric field at the centre of the square is along
What is the energy stored in the capacitor between terminals a and b of the network shown in the figure? (Capacitance of each capacitor C = 1 ??)
$2$-Phenylethylbromide when heated with $NaOEt$, elimination takes place. No deuterium exchange takes place when the reaction is carried out in $C_2H_5OD$ solvent. The mechanism will be
How many geometrical isomers are possible in the following two alkenes ? (i) $\quad$$CH_3 - CH = CH - CH = CH - CH_3$ (ii) $\quad$$CH_3 - CH = CH - CH = CH - Cl$
Mercurous chloride exists in the form of
Electromeric effect is brought into play only at the requirement of the reagent. It is a temporary effect in which bond pair is shifted to one of the constituent atoms.

Given below are two statements, one is labelled as Assertion A and the other is labelled as Reason R

Assertion (A) : \(C _{2} H _{5} Br\) reacts with alcoholic solution of \(AgNO _{2}\) to form nitroethane as the major product.

Reason (R) \(: NO _{2}^-\) is an ambidient ion.

In the light of the above statements, choose the correct answer from the options given below

When nitric acid reacts with nitric oxide, a gas is released, which converts $H _{2} S$ into
Neglecting the density of air, the terminal velocity obtained by a raindrop of radius $0.3\, mm$ falling through air of viscosity $1.8 \times 10^{-5}\, N \,s \,m ^{-2}$ will be
During an allergic reaction, the binding of antigens to $IgE$ antibodies initiates a response, in which chemicals cause the dilation of blood vessels and a host of other physiological changes. Such chemicals are
When NO reacts with $FeSO _{4}$, a brown coloured complex is formed. In the complex, the coordination number of Fe is $+6$.
The value of van der Waals' constant ' $a$ ' for ammonia is larger than that of nitrogen gas. Molecular weight of ammonia is smaller than nitrogen gas.
Pollen mother cells (PMCs) are the first male gametophytic cells. Each PMC gives rise to two pollens.
For the reaction, $2 NO (g)+ O _{2}(g) \rightleftharpoons 2 NO _{2}(g),$ increase in pressure favours the formation of $NO _{2}$. The reaction is exothermic.
