Hi Yogesh,
In Apex Code, null actually doesn't count as any bytes (per se). However, when you add null to a string, it's typed coerced into a string four-characters long-- "null". This behavior seems to be rather specific to Apex Code. In other languages that allow null bytes in a string, null should actually be one byte long.
