Here's a question:
if you consider a connected body with a massless string, and then calculate the tension on the string, you'll get an uniform answer. say, let the tension be "x" newton. the value of x has to be a positive real number.
explain this phenomenon, { since the string is massless, tension, being a force, should be equal to 0 }

Force doesn't account for mass.
Mass is only a factor when considering forces in relation to gravity.
Are you mixing up force and accelaration?
