4.2m/s. Momentum=mass x velocity so 275/65=velocity=4.23
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 
Alessandro Volta's battery was a simple and reliable source of electric current, which allowed scientists to study electricity better than they could with previous sources, such as the Leyden jar, and allowed the development of new technology powered by electricity.
Work is performed while initially lifting books off the floor. The work is due to gravity.
It [the diamond] would act like a prism, and make a rainbow, or, the light would break up and disappear
