A spring is placed between the jaws of screw gauge such that the spring is not all compressed. The mai scale reads 2 division and circular scale reads 28 divisions. Now we turn the circular scale by 18^(@) such that the spring is compessed. The circular scale has 200 divisions and the least count of the main scale is 1mm. What is the force exerted by the spring on the jaws if the spring constnat is 100N//m
