Explanation: it gets dimmer becuase less light......
The answer would be conduction. hope that helped
Answer:
√ ae/ ap = √ mp/me 1/2
Explanation:
Mass of the electron = M (Given)
Mass of the proton = M (Given)
Time = t (Given)
<h3>Electrostatic force, FE = eE (for </h3><h3>both electron and proton)</h3>
But acceleration of electron, ae =FE/me whereas
acceleration of proton, ap = FE/mp
S = 1/2at²1 = 1/2apt²2
<h3>Therefore,</h3>
t2/t1= √ ae/ ap
t2/t1= √ ae/ ap = √ mp/me 1/2
<h3>Thus, the ratio is nearly equal to</h3><h3> = √ ae/ ap = √ mp/me 1/2</h3>
<h2>so, option D is correct</h2>
