Question
A wire is 4 m long and has a mass 0.2 kg. The wire is kept horizontally. A transverse pulse is generated by plucking one end of the taut (tight) wire. The pulse makes four trips back and forth along the wire in 0.8 sec. The tension in the wire will be -
Options
A.80 N
B.160 N
C.240 N
D.320 N
Solution
t =
⇒ v = 
= 40m / sv =
⇒ T = μv2 = 
× (40)2 =
= 80 NCreate a free account to view solution
