A circular plate of diameter a is kept in contact with a Square Plate of age as shown in figure the density of the material and thickness are the same everywhere the centre of mass of the composite system will be
Answers
Answer:
Explanation:
(b) inside the square plate
Let m1 be the mass of circular plate and m2 be the mass of square plate.
The thickness of both the plates is t.
mass = density × volumem1 = ρπ(d2)2t m2 = ρd2t mass = density × volumem1 = ρπd22t m2 = ρd2t
Centre of mass of the circular plate lies at its centre.
Let the centre of circular plate be the origin.
r→1=0r→1=0
Centre of mass of the square plate lies at its centre.
r→2=2dNow,R = m1r→1 + m2r→2m1 + m2 = m1 × 0 + ρd2t × 2dρπ(d2)2t + ρd2t = 2dπ4 + 1 = 1.12d⇒R>dr→2=2dNow,R = m1r→1 + m2r→2m1 + m2 = m1 × 0 + ρd2t × 2dρπd22t + ρd2t = 2dπ4 + 1 = 1.12d⇒R>d
∴∴ Centre of mass of the system lies in the square plate.
