Answer:
0.5 m
Explanation:
Two charges each of magnitude q
Let the third charge is Q is placed at a distance x from the origin so that the charge is in equilibrium.
The force on Q due to q at origin is balanced by the charge on Q due to the charge q placed at x = 1 m.
So,

1 - x = x
1 = 2x
x = 0.5 m
Thus, the third charge is placed at x = 0.5 m .

Answer:
Reverse Osmosis and UV Treatment
Explanation:
Reverse Osmosis, commonly known as RO, process is very effective in removing salt content from water. This process is known as desalination. IN RO, a partially permeable membrane is used to remove unwanted molecules, ions, and large particles. RO will take care of both desalination and purification of water.
Further UV treatment can be done to kill any remaining microorganisms as these microorganisms can not withstand UV radiation.
