A π_ ("pi-minus") particle, which has charge _e, is at location ‹ 4.00 10-9, -5.00 10-9, -2.00 10-9 › m. What is the electric field at location < -2.00 10-9, 4.00 10-9, 3.00 10-9 > m, due to the π_ particle?

The electric field due to charge at distance r is

Explanation:

Given that,

Initial position of particle

Final position of particle

We need to calculate the magnitude of the position vector

Using formula of position vector

Put the value into the formula

We need to calculate the unit vector along electric field direction

Using formula of unit vector

Put the value into the formula

We need to calculate the electric field due to charge at distance r

Using formula of electric field

Put the value into the formula

Hence, The electric field due to charge at distance r is
