Complete Question

A proton is located at <3 x 10^{-10}, -5*10^{-10}  , -5*10^{-10}> m. What is r, the vector from the origin to the location of the proton

The  vector position is  

Explanation:

From the question we are told that

  The  position of the proton is

Generally the vector location of the proton is mathematically represented as

So substituting values
