A proton is given an acceleration of 1.5x109 m/s² when it is placed in an electric field. What is the strength of the electric field?

The strength of the electric field is

Explanation:

Here the electric force is equal to Newton's second law.

Let's recall that electric force is the electric field times the charge, so we have:

(1)

Where:

m is the proton mass

q is the proton charge

a is the acceleration        

Using the equation (1) we have:

Therefore, the strength of the electric field is

I hope it helps you!

he . if i may ask what i your question exactly?

explanation:

it is called kinetic energy
