Question

Two strings A and B made of same material are stretched by same tension. The radius of string A is double of the radius of B. A transverse wave travels on A with speed `v_A` and on B with speed `v_B`. The ratio `v_A/v_B` is
A. `(1)/(4)`
B. `(1)/(2)`
C. 2
D. 4

Answer 1

Correct Answer - B
`(V_(A))/(V_(B))=(r_(B))/(r_(A))sqrt((T_(A))/(T_(B))xx(p_(B))/(p_(A)))=(1)/(2)`
