Answer:
306500 N/C
Explanation:
The magnitude of an electric field around a single charge is calculated with this equation:

With ε0 = 8.85*10^-12 C^2/(N*m^2)
Then:

E(0.89) = 306500 N/C
 
        
             
        
        
        
Answer:
Acceleration of proton will be 
Explanation:
We have given a proton is placed in an electric field of intensity of 700 N/C
So electric field E = 700 N/C
Mass of proton 
Charge on proton 
So electric force on the proton 
This force will be equal to force due to acceleration of the proton 
According to newton's law force is given by F = ma
So 

So acceleration of proton will be
