How does the Width of the deflection region of a pn junction vary, if the reverse bias applied to it decreases?

IF THE REVERSE BIAS APPLIED TO PN JUNCTION IS REDUCED THAN IT”S DEPLETION REGION WIDTH DECREASE...
WIDTH IS proportional TO SEQURE ROOT OF APPLIED REVERSE BIAS VOLTAGE..
THIS HAPPENS BECAUSE ELECTRIC FIELD IN THE DEPLETION REGION DECREASES.
Adarsh
In reverse biasing the potential drop across deplition region increases , thus the deplition region is widened and its field become stronger...

The length of a massless rod is measured using vernier callipers having 10 vernier scale divisions and least count of 0.1 mm. Two masses 1.00 ± 0.01 kg and 4.00 ± 0.02 kg are attached to its ends. If reading of vernier scale is 5 divisions coinciding with 1.3 cm, what is the % error in locating centre of mass from lighter mass
