The truth table for the given logic circuit is:

The incorrect statement regarding chirality is:

A radioactive nucleus ${}_{\mathrm{Z}}^{\mathrm{A}}\mathrm{X}$ undergoes spontaneous decay in the sequence  ${}_{\mathrm{Z}}^{\mathrm{A}}\mathrm{X}\to {}_{\mathrm{Z}-1}\mathrm{B}\to {}_{\mathrm{Z}-3}\mathrm{C}\to {}_{\mathrm{Z}-2}\mathrm{D}$ , where $\mathrm{Z}$ is the atomic number of element $\mathrm{X}$ . The possible decay particles in the sequence are:

An infinitely long straight conductor carries a current of $5\mathrm{A}$ as shown. An electron is moving with a speed of ${10}^5\mathrm{m}/\mathrm{s}$ parallel to the conductor. The perpendicular distance between the electron and the conductor is $20\mathrm{c}\mathrm{m}$ at an instant. Calculate the magnitude of the force experienced by the electron at that instant.

Given below are two statements:

Statement I:
In the coagulation of a negative sol, the flocculating power of the three given ions is in the order- Al³⁺ > Ba²⁺ > Na⁺

Statement II:
In the coagulation of a positive sol, the flocculating power of the three given salts is in the order NaCl > Na₂SO₄ > Na₃PO₄

In the light of the above statements, choose the most appropriate answer from the options given below:

Given below are two statements:

Statement I:
Primary aliphatic amines react with HNO₂ to give unstable diazonium salts.

Statement II:
Primary aromatic amines react with HNO₂ to form diazonium salts which are stable even above 300 K.

In the light of the above statements, choose the most appropriate answer from the options given below:

Two point charges $-\mathrm{q}$ and $+\mathrm{q}$ are placed at a distance of L, as shown in the figure.

The magnitude of electric field intensity at a distance $R(R>>L)$  varies as :

A big circular coil of 1000 turns, and average radius 10 m is rotating about its horizontal diameter at 2 rad ${\mathrm{s}}^{-1}$ . If the vertical component of earth's magnetic field at that place is $2*{10}^{-5}\mathrm{T}$ and electrical resistance of the coil is $12.56\mathrm{\Omega }$ , then the maximum induced current in the coil will be:

The area of rectangular field (in ${\mathrm{m}}^2$ ) of length $55.3\mathrm{m}$ and breadth 25 m after rounding off the value of correct significant digits is:

The graph which shows the vartiation of the de-Broglie wavelength $\left(\lambda \right)$  of a particle and its associated momentum (p) is :
