Aproton is located at 7 ✕ 10−10, −2 ✕ 10−10, −2 ✕ 10−10 m. (a) what is r, the vector from the origin to the location of the proton?

The distance r is

Explanation:

Given that,

Origin

Position of proton

Here, r is the distance from origin to the location of the proton

We need to calculate the distance

Using formula of distance

Where, r₁= origin

r₂ = position of proton

Put the value into the formula

Hence, The distance is
