When tenion in a metakl wire is `T_(2)`, its length was `l_(1)` and when tension is `T_(2)` the length is `l_(2)` . Find its unstreched length .

When the tension in a metal wire is T_(1) , its length is I_(1) . When the tension is T_(2) , its length is I_(2) . The natural length of wire is

When the tension in a metal wire is T_(1) , its length is I_(1) . When the tension is T_(2) , its length is I_(2) . The natural length of wire is

When the tenstion on a wire is 4N its length is l_(1) . When the tension on the wire is 5N its length is l_(2) . Find its natural length.

When the tension on a wire is 4N its length is l_(1) . When the tension on the wire is 4N length is l_(1) . When the tension on the wire is 5N its length is l_(2) . Find its natural length.

The length of metallic wire is l. The tensin in the wire is T_(1) for length l_(1) and tension in the wire is T_(2) for length l_(2). Find the original length.

The length of a metal wire is l_(1) when the tension in it is T_(1) and is l_(2) when the tension is T_(2) . Then natural length of the wire is

The length of a metal wire is l_(1) when the tension in it is T_(1) and is l_(2) when the tension is T_(2) . The natural length of the wire is:

The length of a metal wire is l_(1) when the tension in it is T_(1) and is l_(2) when the tension is T_(2) . Then natural length of the wire is
