EXE.1A.HL.TZ0.8

Two objects of mass $M$ each are connected by a weightless rod of length $d$ . A force $F$ is applied to each of the objects, at right angles to the rod as shown.

What is the torque acting on the system about the midpoint of the rod and what is the angular acceleration of the system?

	Torque	Angular acceleration
A.	$F d$	$\frac{2 F}{M d}$
B.	$F d$	$\frac{4 F}{M d}$
C.	$2 F d$	$\frac{2 F}{M d}$
D.	$2 F d$	$\frac{4 F}{M d}$
