Experiment to show that force applied is directly proportional to the extension of a spring.

Name: ...............................................Class: .....................

Apparatus used: A lab stand Two clamps A metre rule Slotted masses of 25 g with hanger A spring

Procedure:1. The metre rule is placed vertically on the bench using the clamp. The spring is placed

in front of the metre rule as shown.2. The readings lA and lB are noted down. Length of spring = 3. A 25 g mass hanger is hung on the spring.4. The new readings lA and lB are noted.5. A 25 g mass is further added and step 4 is repeated.
