One block having a mass of 0.32 kg are connected by a wire CD and the system is suspended from the ceiling by wire CD(figure). The linear mass density of the wire CD is `8g//m`. The speed of a transverse wave pulse produced in CD is: `(g=10m//s^2)`

Options

A. 20 m/s
B. 200 m/s
C. 400 m/s
D. 40 m/s

Answer

A

Explanation

`V_(CD)=sqrt((0.32xx10)/(8xx10^(-3))) =sqrt(400)= 20 m//s`
