ANSWER

Step-by-step explanation
(a) To find the force acting on the proton, we have to apply the formula representing the relationship between electric field and electric force:

where q = charge of the proton
E = electric field
The charge of a proton is:

Hence, the force acting on the proton by the electric field is:

(b) To find the acceleration of the particle, apply the relationship between force and acceleration:

where m = mass; a = acceleration
The mass of a proton is:
![m=1.67\cdot10^(-27)\operatorname{kg}]()
Hence, the acceleration of the proton is:
