Question

he pitch of the screw gauge is 1 mm. There are 100 divisions on the circular scale when the gap AB is just closed, 8th division of the circular scale coincides with reference line. While measuring the diameter of a wire, the linear scale reads 1 mm and 50th division on the circular scale coincides with the reference line. The length of the wire is 8.6 cm. Find the curved surface area of the cylinder
a. 3.8 cm2
b. 3.834 cm
C. 2.6 cm
d. 2.68 cm2​

Answer 1

Answer:

Least can be defined as the ratio of the pitch of the screw gauge to the number of divisions in the circular scale. Pitch of the screw gauge is 1mm and the number of divisions in the circular scale is 100. Length of the wire is given as l = 5.6 cm.

Answer 2

Explanation:

Least can be defined as the ratio of the pitch of the screw gauge to the number of divisions in the circular scale. Pitch of the screw gauge is 1mm and the number of divisions in the circular scale is 100. Length of the wire is given as l = 5.6 cm.
