Answer:

(a)Zero error of vernier: If the zero of vernier scale and zero of the main scale do not coincide, when the external jaws of verniers are closed, the vernier is said to have zero error.

(b) (i) Positive zero error of vernier: If the zero of the vernier scale is on the right hand side of the zero of main scale, the error is said to be positive error.

     (ii) Negative zero error of vernier: If the zero of the vernier scale is on the left hand side of the zero of main scale, the error is said to be negative error.

(c) (i) Correction= -( 7 x 0.01cm) = -0.07 cm.

     (ii) Correction= +(7 x 0.01cm) = +0.07 cm.
