Question

A block B of mass 10 kg is placed on smooth horizontal surface over it another block A of same mass is placed. A horizontal force F is applied on block B

S1 : No block will move unless F > 10 N.
S2 : Block A will move towards left.
S3 : Acceleration of block B will never be less than that of A.
S4 : The relative motion between A and B will start when F exceeds 10 N.

  1. F F F F    
  2. T T T T    
  3. F F T F    
  4. T T F F    

The correct answer is: F F T F

The cations and anions formed as a result of electron transfer are drawn towards each other due to the electrostatic force (coulomb force) of attraction. They form an ionic bond or an electrovalent bond. The bond between two elements is ionic if the EN difference between them is greater than 1.7. The number of electrons transferred during an ionic bond formation is known as an electrovalency. Compounds containing ionic bonds are called ionic compounds. Examples of ionic compounds are NaCl(Na+Cl), CaO(Ca2+O2–), MgO(Mg2+O2–) and MgCl2 open parentheses C l to the power of minus end exponent M g to the power of plus plus end exponent C l to the power of minus end exponent close parentheses.
Element X is strongly electropositive and the element Y is strongly electronegative. Both are univalent. The compound formed would be:
