Is the extension of a spring directly proportional indirectly proportional or inversely proportional to the force applied

For a given object, extension of string is directly proportional to the force applied. This means extension increases on increasing the force applied.

Explanation:

The extension of an elastic object such as spring is described by Hooke's law, Hooke's law says that the force required to extend or compress the spring by any distance increases or decreases directly to the distance to which it is extended or compressed. F = K e

where,

K is Spring constant

F is Force applied

and e is the length of the string to be increased or decreased
