The incorrect statement is option 3.
Let's check out the given options:
(1) 1nm = 10^(-9)m
This option is correct because 1 nanometer is equal to 10 raised to power -9 meters.
(2) 1pm = 10^(-12)m
This option is correct because 1 picometre is equal to 10 raised to power -12 meters.
(4) Both (1) and (2)
This option is correct because both options (1) and (2) are correct.
(3) 1 mg = 10^(-3)m
This option is incorrect because 1 mg is equal to 10 raised to power -6 meters and not 10 raised to power -3 meters.
Hence, this option is incorrect.
This is the final result. Option (3) 1 mg = 10^(-3) kg is incorrect.
