Question

determine the least count of the vernier calipers and measure the length and diameter of a small cylinder (average of three sets)-may be a metal rod of length 2 to 3 cm and diameter 1 to 2 cm​

Answer 1

Answer:

Vernier callipers.A spherical body (it can be a pendulum bob)A cylinder.A small rectangular metallic block of known massA beaker or a calorimeter. The Procedure

1 M.S.D. 1 mm

10 V.S.D. 9 M.S.D.

1 V.S.D. 9/10 M.S.D. = 0.9 mm.

Vernier Constant, V.C.= 1 M.S.D.-1 V.S.D. = (1-0.9) mm = 0.1 mm = 0.01cm.
