5) Make the measurement equal by conversion. 2000 g = 2 kg 14000m = 14 km mm = 160 cm 0.8 m = cm 109 g = kg kg = 5.6 g L = 75 mL 16.5mm = cm

Explanation:

The relevant conversion factors are ...

  1 m = 100 cm

  1 cm = 10 mm

  1 kg = 1000 g

  1 L = 1000 mL

These are based on the meanings of the SI prefixes:

  centi- = 1/100

  milli- = 1/1000

  kilo- = 1000

__

2000 g = 2 kg --- given

14000m = 14 km --- given

1600 mm = 160 cm

0.8 m = 80 cm

109 g = 0.109 kg

0.0056 kg = 5.6 g

0.075 L = 75 mL

16.5mm = 1.65 cm

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
