1. is there any lower limit to the electric force between two particles placed at a seperation of 1 cm ? 2.in some old text it is mentioned that 4(pie) lines of force originate from each unit positive charge . Comment on the statement in view of the fact that 4(pie) is not an integer.

εεεelectric charge is quantized and the least force is that between two quanta. the flux of the electric field across a surface is defined as the area multiplied by the intensity of the field in the direction normal to the area, multiplied by 4πε0. for a unit positive charge at the centre of a sphere of radius 'r', the flux is (1/(4πε0r2)(4πr2)(4πε0)=4π, it is technically incorrect to say

"4(pi) lines of force..." you will not find such mistakes in good books like Resnick and Halliday

my sincere regards to you sir but I think that in question 2, it is about a common old theory that you may not know, after all H. C. Verma is a reputed book, we can’t challenge it’s question.
