Question 4

Two particles C C\,C of mass 3 kg and D D\,D of mass 5 kg are connected by a light inextensible string. The string passes over a smooth pulley fixed at the top of a rough inclined plane. The plane is inclined at an angle of 35∘ 35^\circ\,35∘ to the horizontal. C C\,C lies at rest on the plane and D D\,D hangs freely from the edge of the plane with the string taut. Particle C C\,C is released from rest and accelerates up the plane at 2 ms-2.

a.

Find the tension in the string

[3]
b.

Find the coefficient of friction between C C\,C and the plane

[3]
c.

Find the force exerted on the pulley by the string
