P block l-2

P block elements

P block elements

In Fig block 1 is placed on top of block 2 .Both of then have a mass of 1 kg The coefficient of friction between block 1 and 2 are mu_(s) = 0.75 and mu_(k) = 0.60 The table is frictionless A force p//2 is applied on block 1 in the left and force P on block 2 to the right .Find the minimum value of p such that sliding accore between the two blocks

Which of the following is most electronegative in p -block elements

p block elements of 6^(th) period are represented as :-

Give two characteristics of p -block elements.

Assertion:- The heavier P-block elements form storng pi- bonds. Reasons:- The heavier elements of p-block form dpi-p pi or dpi-dpi bonds.

A block of mass m compresses a spring iof stifffness k through a distacne l//2 as shown in the figure .If the block is not fixed to the spring the period of motion of the block is
