Aproton accelerates from rest in a uniform electric field of 680 n/c. at one later moment, its speed is 1.30 mm/s (nonrelativistic because v is much less than the speed of light). (a) find the acceleration of the proton.

Acceleration,                                                

Explanation:

Given that,

Electric field, E = 680 N/C

Speed of the proton, v = 1.3 Mm/s

We need to find the acceleration of the proton. We know that the force due to motion is balanced by the electric force as :

a and m are the acceleration and mass of the proton.

So, the acceleration of the proton is . Hence, this is the required solution.
