The answer is V/L.

We know V=Rw, where V is the linear velocity, R is radius, w is angular velocity.

Given, 2 equal masses are held at the ends. Also, Impulse,F= MV.

ie the velocity of action is V.

Therefore, by question

V=Lw

or w=V/L

Hope you understood!

OPTION NO: A because
w=j1/2
2m*(1/2)^2=mv*1/2
w=v/l
 
THIS HAVE BEEN DONE !!
BECAUSE THE COMPUTER HAVE TO HAVE 100 CHAR

Iw=MvL
w=MvL/I
I=ML*L
w=MvL/ML*L
    =v/L
w=v/L
As one mass is given the force itself and it is at one 
end its moment of inertia is zero.
The axis of rotation passes through the other end of the rod.
