Answer:
Height of coffee mug = 5 cm
Explanation:
Changing all the data given in to unit cm
50 mm = 5 cm
20 cm = 20 cm
8 m = 800 cm
0.1 km = 100 m = 10000 cm
Since we need to find the height of coffee mug, it's height will not be more than 10 cm.
So 5 cm is the correct choice.

When Rutherford did the Gold Foil experiment, he expected that most of his alpha particles will go straight through, without any major deflections. He noticed that, during the experiment, most alpha particles went straight through, but was surprised to see that some got deflected by major angles. So he came up with a theory which states that every atom has got a nucleus, and also stated that most parts of the atom are empty, as most of the particles went through.
