When a cylinder is gripped between the
Vernier calepers, zero of vernier scale lies
between 7.5 cm and 7.6cm , 28th division of
Vernier scale matches with any one division of
main scale, vernier scale has total 40 divisions.
on it. Then calculate the L.c. of Verrnier
calipers and diameter of the cylinder.​
