If string is stretched by two opposite forces of 10 N then tension in string is

Consider a stretched string under tension and fixed at both ends. If the tension is doubled and the cross-sectional area halved, then the frequency becomes

Determine the correctness or otherwise of the following Assertion (a) and Reason (r). Assertion : During rolling, front tension and (or) back tension are (is) employed to decrease rolling load. Rea

Two identical straight wires are stretched so as to produce 6 beats per second when tension slightly in one of them, the beat frequency remains unchanged. Denoting by T1 and T2 the higher and lower

The radius, density and tension of a string A are twice the radius, density and tension of another string B. If the lengths of the string are equal, the ratio of their frequencies of their vibration (

The length of an elastic string is a metre when the tension is 4 N, and b metre when the tension is 5 N. The length in metres when the tension is 9 N, is

The length of an elastic string is a metre when the tension is 4 N, and b metre when the tension is 5 N. The length in metre when the tension is 9 N is
