The length of a light string is 1.4 m when the tension on it is 5 N. If the tension increases to 7 N , the length of the string is 1.56 m. The original length of the string is _____ m.

Correct answer

0

Step-by-step solution

aligned & T = K ( - ₀ ) & 5= K (1.4- ₀ ) & 7= K (1.56- ₀ ) & 5 1.4- ₀ = 7 1.56- ₀ & ₀=1 ~m aligned
