[A] : Soil particles , particularly clay and organic matter in soil , contain negative charges that attract positively charged ions such as `Ca^(++) , K^(+)` and `Mg^(+ +)`
[R] : This attraction keeps these ions at a soil level where they are available to plants .

soil particles, particularly clay and organic matter in soil , contain negative charges and attract positively charged ions, such as:

Assertion: Among isoelectronic species, the cation with the greater positive charge will have a smaller radius. Reason :Greater is the attraction of the electrons to the nucleus, smaller is the size of atom/ion.

A : ESP can remove the particulate matter by more than 99%. R : Anode attract the partioles and provie positive charge the same & allow them to fall.

Write the following steps is sequence that explain the phenomenon of redistribution of charges in an unchanged body in presence of a charged body . (A) As a result at one of the neutral body there is and excess of negatively charged particles and the other end there is an excess of positively charged particles. (B) Place a positively charged body near a neutral body. (C ) The negatively and positively chargeed particles in the neutral body get attracted and repelled by the positively charged body .
