A compound of vanadium has a magnetic moment 1.73 B. M. The electronic configuration of vanadium ion in the compound is -

The following graph between probability density and distance from the nucleus represents -

In the following transition which statement is correct

For H atom, the energy required for the removal electron from various sub-shells is given at under:

The order of the energies would be:

The uncertainty in the position of an electron (mass ) moving with a velocity of sec^-1, accurate upto 0.011% will be

A block of mass M slides down a smooth inclined plane of height h through a slope distance s. The kinetic energy of the mass at the bottom will be

A rod of mass M and length L is lying on a horizontal table. The work done in making it stand e one end will be

A particle starts with velocity u and moves with constant acceleration a what is the nature of the graph between the time (t) and the displacement (x).

The positive integers are written in a triangular array as shown

The row in which the number 2005 will be, is

nth term of the given sequence should be less than or equal to 2005  since the number 2005 can be anywhere in the whole row but atleast at the 1st position.

P is a point inside the triangle ABC. Lines are drawn through P parallel to the sides of the triangle. The areas of the three resulting triangles with a vertex at P are 4, 9 and 49, then the area of ABC is

ratio of sides of similar triangles = square root of the ratio of areas of the triangles. the converse is also true.

ABC is an isosceles right angled triangle with AB = BC = 1. If P is any point on BC, then min {max{(area APQ), (area PQBR), area PRC)}} is

the minimum function gives us the minimum of the values passed to it . similarly, the max or maximum function returns the maximum of the values passed to it.

An electron is moving along the positive X-axis. You want to apply a magnetic field for a short time so that the electron may reverse its direction and move parallel to the negative X-axis. This can be done by applying the magnetic field along

A current carrying wire LN is bent in the from shown below. If wire carries a current of 10 A and it is placed in a magnetic field of 5T which acts perpendicular to the paper outwards then it will experience a force

Figure shows a straight wire of length l current i. The magnitude of magnetic field produced by the current at point P is

In figure shows three long straight wires P, Q and R carrying currents normal to the plane of the paper. All three currents have the same magnitude. Which arrow best shows the direction of the resultant force on the wire P

A wire carrying a current i is placed in a uniform magnetic field in the form of the curve The force acting on the wire is
