The magnitude of the magnetic field (B) due to loop ABCD at the origin (O) is
The electrophile, E⊕ attacks the benzene ring to generate the intermediate σ−complex. Of the following, which σ-complex is of lowest energy ?
Statement-I: For a mass M kept at the centre of a cube of side gravitational field passing through its sides is 4π GM. And
Statement-II : If the direction of a field due to a point source is radial and its dependence on the distance 'r' for the source is given as 1/r2, its flux through a closed surface depends only on the strength of the source enclosed by the surface and not on the size or shape of the surface.
Consider a family of circles which are passing through the point (−1,1)and are tangent to x-axis. If (h, k) are the co-ordinates of the centre of the circles, then the set of values of k is given by the interval
In which of the following octahedral complexs of Co (at. No. 27), will the magnitude of Δo be the highest ?
Consider a rubber ball freely falling from a height h = 4.9 m onto a horizontal elastic plate. Assume that the duration of collision is negligible and the collision with the plate is totally elastic. Then the velocity as a function of time the height as function of time will be
