Problem

A transverse wave travels on a taut steel wire with a velocity of

v

when tension in it is

2.06 \times 10^4

N. When the tension is changed to

T

, the velocity changed to

v/2

. The value of

T

is close to: (1)

2.50 \times 10^4

N (2)

5.15 \times 10^3

N (3)

30.5 \times 10^4

N (4)

10.2 \times 10^2
