Question

Two beads P and Q, free to slide on a smooth light horizontal rod, are connected by a
string (between P and Q) of lengthl = 2.5m. Masses of the beads are
mp = 2 kg and me = 3 kg respectively. The whole setup is rotated with an angular velocity
o=1rad / s about a vertical axis such that the system of beads is in equilibrium with
respect to the rotating rod. Then, tension in the connecting string PQ is
Р

Answer 1

Answer:

Explanation:

is called a newton (N), and from F = ma we see that 1 N = 1 kg m/s2. ... The friction force between two objects is extremely complicated on a ... a free-body diagram shows all of the external forces (that is, forces due to ... A mass m is connected to the end of a massless string of length ℓ. ... i = 2ad, or d = v0t − at2/2 with t =.
