الحل أهو
As V= Gazr tarbeeee3y le Ft / m
And As Here There Is No Weight So, V = gazr g / m
And As m = M/ (L - X) ........ So V = gazr( L - X )g / M
And As M is Negligible amount

it could be estimated as (1) And This is because Ft = g in this case
so V = gazr (L-X) g
and this is proved !!!!!!!!!!!!!!!!!!!
