As proton is heavier then electron, and electrostatic force is directly proportional to mass, so it would be greater and direction would be changed 'cause of different charges.
In short, Your Answer would be Option 4
Hope this helps!

Answer:
Green part of the visible spectrum.
X ray part of the electromagnetic spectrum.
Infrared part of the electromagnetic spectrum.
Explanation:
Wien's displacement law
Where, b = Wien's displacement constant = 2.898×10⁻³ mK
T = Temperature in kelvin
So, the wavelength would be of around the green part of the visible spectrum.
So, the wavelength would be of around the X ray part of the electromagnetic spectrum.
Human body temperature = 37°C = 37+273.15 = 310.15 K
So, the wavelength would be of around the Infrared part of the electromagnetic spectrum.
Question: A ship anchored at sea is rocked by waves that have crests 100 m apart the waves travel at 70m/S, at what frequency do the waves reach the ship?
Answer:
0.7 Hz
Explanation:
Applying,
v = λf............... Equation 1
Where v = velocity of the wave, f = frequency fo the wave, λ = wavelength of the wave
make f the subject of the equation
f = v/λ................. Equation 2
From the question,
Given: v = 70 m/s, λ = 100 m ( distance between successive crest)
Substitute these values into equation 2
f = 70/100
f = 0.7 Hz
Hence the frequency at which the wave reach the ship is 0.7 Hz
