which means
Answer:
The acceleration of proton will be 
Explanation:
We have given electric field E = 450 N/C
Charge on proton 
Force on electron due to electric field is given by 
Mass of electron 
Now according to second law of motion 
So 
So the acceleration of proton will be

➷ Use this equation:
Q = IT
Rearrange for I
I = Q/T
Substitute in the values:
I = 240/3
I = 80
The electric current is 80 amps.
