Two masses, mi= 1 kg and m3= 5 kg, are connected by a rigid rod of negligible weight (see Fig). The system is
pivoted about point 0. The gravitational forces act in the
negative z direction.(a) Express the position vectors and
the forces on the masses in terms of unit vectors and
calculate the torque on the system. (b) What is the
angular acceleration of the system at the instant shown
in Fig?

concave lenses are used here. they spread the light out before it reaches the convex lens in the eye, therefore letting the image focus directly on the retina. hyperopia is known to you probably as farsightedness.
