Consider the following four elements, which are represented according to long form of periodic table Here W, Y and Z left, up and right elements with respect to the element 'X' and 'X' belongs to 16^("th") group and 3^("rd") period. Then according to given information the incorrect statement regarding given elements is
In a thin rectangular metallic strip a constant current I flows along the positive x-direction , as shown in the figure. The length , width and thickness of the strip are l, w and d , respectively. A uniform magnetic field vec(B) is applied on the strip along the positive y- direction . Due to this, the charge carriers experience a net deflection along the z- direction . This results in accumulation of charge carriers on the surface PQRS ansd apperance of equal and opposite charges on the face opposite to PQRS . A potential difference along the z-direction is thus developed. Charge accumulation contiues untill the magnetic force is balanced by the electric force. The current is assumed to be uniformly distributed on the cross- section of the strip and carried by electrons. Consider two different metallic strips (1 and 2) of the same material . Their lengths are the same,widths are w_(1) and w_(2) and thickness are d_(1) and d_(2) respectively. Two points K and M are symmetrically located on the opposite faces parallel to the x-y plane ( see figure) . V_(1) and V_(2) are the potential differences between K and M in strips 1 and 2 , respectively . Then, for a given current I flowing through them in a given magnetic field strength B , the correct statement(s) is (are)
