Question

the force of attraction between earth and body of 1 kg is

Answer 1

hi the answer is 9.8 N means 10 N

Answer 2

The simple answer of your question is "9.8 N"
This is because we know that the force of attraction by the earth for a object close to earth and pulling by the earth is illustrated by the formula 
F=mg 
 here F=force of gravity (attraction ) pulling the object
m= mass of object   and
g is acceleration due to gravity which remains constant 9.8 m/s2
 
We have given the value of mass as the 1 kg

Now just put the values in the formula F= m*g = 1* 9.8 =  9.8 N
hence the the answer is 9.8 N
