Questions
The diameter of a metal ring is and coefficient of linear expansion is , if the temperature of the ring is increases by , The circumference of the ring will increase by where
detailed solution
Correct option is A
circumference of ring is S=2πR=2πD2 S=πD differentiate ΔS=πΔD coefficient of linear expansion α=ΔDDΔt⇒ΔD=DαΔt;ΔS=xπDα ; substitute in above equation xπDα=πDαΔt x=Δt given Δt =1 ⇒x=1Similar Questions
