A)the tension in first string is now a)T/2 b)T c)2T B)The speed of a wave on the first string would now be a)underroot v/2 b)v/underroot 2 c)v/2 d)v e) underroot 2v
A string is stretched horizontally between a fixed point and a frictionless pulley,the string passes over the pulley and an object of mass m is hanging from the end of string.the tension in the string is T and speed of a wave on this string is v.A second string is connected beside the first ,passes over the same pulley,and then is attached to same object . Assuming both strings support the object equally. A)the tension in first string is now a)T/2 b)T c)2T B)The speed of a wave on the first string would now be a)underroot v/2 b)v/underroot 2 c)v/2 d)v e) underroot 2v
