See friend.
If we do by

10 - 19 = 3a
then its wrong bcoz first of all friction does not impart any
motion to the body.Friction does the job of only opposing da
motion of the body hence,cannot write the equation as so.

and then Force applied < opposition
So only one thing is applicable that body will not move frm
its position.

Hope you find it useful.
Cheers !!!!!!!!!!!!!!!!!!!!!!!!!!!

But Remember Don't hesitate to ask a good Question but
