A) 1 N
B) 4 N
C) 8 N
D) 16 N
Correct Answer: A
Solution :
According to problem \[\frac{1}{2L}\sqrt{\frac{T}{m}}=\frac{v}{4L}\] ?..(i) and \[\frac{1}{2L}\sqrt{\frac{T+8}{m}}=\frac{3v}{4L}\] ..?(ii) Dividing equation (i) and (ii), \[\sqrt{\frac{T}{T+8}}=\frac{1}{3}\Rightarrow T=1N\]You need to login to perform this action.
