Answer:
Β. 16 με
Explanation:
Data provided in the question
Number of electrons removed = 10^14
And, the charge on one electron = 
Based on the above information, the charged on the sphere is
Therefore when we remove the electrons
So, the equation would be
= 
Therefore the same amount of the positive charged would be developed
Hence, the correct option is B.
By uncertainty principle
λ = h / p.
Where λ = wavelength, h = Planck's constant = 6.63 * 10⁻³⁴ Js
λ = wavelength = 550 nm = 550 * 10⁻⁹ m, Mass of electron = 9.1 * 10 ⁻³¹ kg
p = Momentum = mv
λ = h / mv
v = h / mλ
v = 6.63 * 10⁻³⁴ / (9.1 * 10⁻³¹ * 550 * 10⁻⁹)
v = 1 324 675.325 m/s
v ≈ 1.325 *10⁶ m/s
Answer:
V₁ = V = 120 V
Explanation:
Such a combination of capacitors in which;
1- Potential difference across each capacitor is the same
2- Total charge is distributed amongst the capacitors
; is called Parallel Combination.
Therefore, in this case, the potential difference across each capacitor will also be the same. Because the capacitors are connected in parallel here. So the voltage across 3 μF capacitor will be the same as the voltage across the 6 μF capacitor and they both will be equal to the total potential difference.
<u>V₁ = V = 120 V</u>
