Answer: Frequency of 1 ÷ 2 = 0.5 Hz.
A proton repelling another proton
Like charges of the protons would repel one another.
The answer is C, because they moved from a stand still to down the hill
Answer:
Acceleration of proton will be
Explanation:
We have given surface charge density of an infinite charged plate 
Electric field due to infinite sheet charge is given by 
Charge in proton is given by 
So force on proton 
Mass of proton 
According to newtons second law force F = mass × acceleration
So
