Answer:
The magnitude of the magnetic field is 0.156 T.
Explanation:
Given that,
Speed of a proton, 
Radius of the circular path, r = 0.2 m
When the proton enters in the circular path, the centripetal force is balanced by the magnetic force such that :

q is the charge on proton
Here, 

So, the magnitude of the magnetic field is 0.156 T. Hence, this is the required solution.
Farming meant that people did not need to travel to find food.( nomadic lifestyles became scarce) Instead, they began to live in settled communities,or villages and grew crops or raised animals on nearby land. They built stronger, more permanent homes and surrounded their settlements with walls to protect themselves.
